Available in PDF, EPUB and Kindle. Book excerpt: The ability of a space-based radar surveillance system to obtain target information from a clutter corrupted radar echo signal is dependent on the clutter cancellation technique employed. To thoroughly understand the nature of clutter so as to efficiently and effectively design and develop clutter cancellation techniques, fundamental mathematical relationships dealing with radar signal representation, probability theory, detection and estimation theory and signal comparison techniques were established and defined. Since the implementation of the mathematical expressions which describe clutter and clutter cancellation techniques are accomplished digitally, digital signal representation and digital filter characterization via FFt's were also established and defined. Drawing upon the established mathematical principles, as well as temporal probability models, spectral models and average backscatter coefficient models, clutter was described. Capitalizing on the different spectral characteristics between clutter and targets, three representative doppler cancellation schemes were developed. The three schemes were delay line cancelers, doppler filter banks and multiple look systems.

Download or read book Adaptive Clutter Cancellation Techniques for Passive Radars written by Tamás Pető and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In radar systems, the ambiguity function of the applied illuminator signal essentially determines the detection capabilities. Zero Doppler interference (ZDI) or close targets returns can mask weak target reflections from higher distances. This is particularly the case for passive radars where the illuminator signal is not under the control of the radar designer. In recent times, great efforts have been carried out to research and develop efficiently working filter algorithms. These adaptive algorithms aim to cancel the undesired interference components in order to enhance the useful dynamic range. A number of different algorithms are operating in the space and also in the time domain. Spatial algorithms apply beamforming techniques, while temporal algorithms utilize the available reference signal to suppress the interferences. The main goal of this chapter is to present and compare the available spatial and temporal adaptive interference cancellation techniques in terms of filtering efficiency and computation cost on real-life data.
