Download or read book Stap Processing Monostatic and Bistatic Mcarm Data written by and published by . This book was released on 1999 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monostatic airborne radars have a problem detecting low and slow flying airborne targets or slow moving ground targets because of the severe ground clutter. Space Time Adaptive Processing (STAP) algorithms have been found to be effective in suppressing the ground clutter and revealing the targets of interest. Newer surveillance systems, both airborne and space based, are likely to be bistatic, i.e., the transmitter and the receiver are to be housed in separate vehicles. Specifically, the transmitter is to be housed in an AWACS type aircraft or a satellite and the receiver will probably be housed in a UAV. In either case, one is faced with the problem of the same ground clutter as in the monostatic case and thus there is need for bistatic clutter suppression algorithms. In 1995-1996, Air Force Research laboratory, Rome Research Site (AFRL-RRS, formerly Rome Laboratory), collected a large amount of multichannel, airborne radar measurement (MCARM) data, to help verify the efficacy of STAP in both monostatic and bistatic scenarios and if necessary, to develop newer algorithms for the bistatic case. This report documents the efforts by this author to apply and compare the application of STAP algorithms to several acquisitions from both monostatic and bistatic MCARM flights.

Download or read book An Expert System Approach to Bistatic Space time Adaptive Processing written by Alex Burwell and published by . This book was released on 2021 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-Time Adaptive Processing (STAP) is a modern radar signal processing technique that leverages additional Degrees of Freedom (DoF) to cancel clutter from a background environment and produce detections of slow-moving targets. STAP is well-documented and understood; however, bistatic applications, or applications in which a radar transmitter and receiver are physically separated, present additional complications. This work explores techniques in Bistatic Space-Time Adaptive Processing (B-STAP) for Ground-Moving Target Indication (GMTI)---the detection of slow-moving surface targets through ground clutter. Due to the complexity and availability of B-STAP data, the evaluation of bistatic algorithms is challenging. A simulation framework has been created to test and evaluate monostatic and bistatic STAP algorithms, mitigating the lack of representative test data. The framework leverages foundational techniques and characteristics to provide a flexible and extensible mechanism for testing and evaluation. Additionally, the design of a new pluggable bistatic Expert System (ES) processor is presented. The ES leverages existing data excision and warping techniques and pairs them with new Range-Based Compensation (RBC) and Clutter Scoring methods to optimize covariance estimation. The simulation framework is used to evaluate the effectiveness of the ES compared to a variety of previously established bistatic processing techniques. The results validate the approach taken in the ES and provide a path for future exploration.

Download or read book The Eigencanceler Space Time Adaptive Radar by Eigenanalysis Methods written by Alexander Haimovich and published by . This book was released on 1999 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In airborne surveillance radar applications, adaptive antennas provide for the detection of small targets in severe clutter environments. Adaptive antennas are currently being considered for the design of next generation surveillance platforms. The radar problem is two-dimensional with radar returns being a function of both angle and Doppler. Space-Time Adaptive Processing (STAP) is required for rejection of interferences in the space-time domains. To make STAP feasible for incorporation into future systems, low complexity algorithms are required. The space-time radar problem is well suited to the application of techniques that take advantage of the low-rank properties associated with the interference in such radars. The Eigencanceler is an interference cancellation method based on the spectral decomposition (eigenanalysis) of the space-time covariance matrix. The linear space spanned by the columns of the space-time covariance matrix is formed by the union of the algebraic spaces of the interference and the noise. The Eigencanceler's weight vector is designed to lie in the noise subspace and to provide a prescribed gain to the desired signal. Thus significant computational savings are realized since a Weiner filter requires a matrix inversion, while the eigencanceler is implemented by computing only a limited number of interference eigenvectors.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard training approach for Space Time Adaptive Processing (STAP) works poorly, especially in cases of non-stationary interference. Bistatic clutter interference exhibits a strongly range-dependent structure. The Derivative-based Updating (DBU) algorithm has an advantage over other algorithms in that no knowledge of transmitter position and velocity are required. The disadvantages of DBU are that it doubles the STAP degrees of freedom, doubles the number of training samples required, and increases the cost of weight computation by a factor of eight. The High-Order Doppler Warning (HODW) algorithm has the advantage of not requiring an increase in degrees of freedom and of being fully adaptable in spatial dimension. The disadvantages of HODW is that it requires knowledge of transmitter position and velocity, increases the complexity of Doppler filtering, and FFT techniques may not be possible with its use. These two algorithms are assessed in Air-to-Air and Space-to-Air bistatic scenarios using covariance analysis and time series analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Radar systems may be processed with various space, time and frequency techniques. Advanced radar systems are required to detect targets in the presence of jamming and clutter. This work studies the application of two types of radar systems. It is well known that targets moving along-track within a Synthetic Aperture Radar field of view are imaged as defocused objects. The SAR stripmap mode is tuned to stationary ground targets and the mismatch between the SAR processing parameters and the target motion parameters causes the energy to spill over to adjacent image pixels, thus hindering target feature extraction and reducing the probability of detection. The problem can be remedied by generating the image using a filter matched to the actual target motion parameters, effectively focusing the SAR image on the target. For a fixed rate of motion the target velocity can be estimated from the slope of the Doppler frequency characteristic. The problem is similar to the classical problem of estimating the instantaneous frequency of a linear FM signal (chirp). The Wigner-Ville distribution, the Gabor expansion, the Short-Time Fourier transform and the Continuous Wavelet Transform are compared with respect to their performance in noisy SAR data to estimate the instantaneous Doppler frequency of range compressed SAR data. It is shown that these methods exhibit sharp signal-to-noise threshold effects. The space-time radar problem is well suited to the application of techniques that take advantage of the low-rank property of the space-time covariance matrix. It is shown that reduced-rank methods outperform full-rank space-time adaptive processing when the space-time covariance matrix is estimated from a dataset with limited support. The utility of reduced-rank methods is demonstrated by theoretical analysis, simulations and analysis of real data. It is shown that reduced-rank processing has two effects on the performance: increased statistical stability which tends to improve performance, and introduction of a bias which lowers the signal-to-noise ratio. A method for evaluating the theoretical conditioned SNR for fixed reduced-rank transforms is also presented.
