Available in PDF, EPUB and Kindle. Book excerpt: Employing the autoregressive (AR) technique and the principle of displaced phase centre antenna (DPCA) we construct an optimum adaptive DPCA processor for moving target detection from airborne phased arrary radar data collected under non- DPCA conditions. It is fundamentally different from the existing adaptive DPCA which is not optimum. The number of range samples it needs to estimate its parameters is only approximately twice the number of antenna elements, significantly smaller than the number required by the conventional space-time adaptive processing (STAP) and other algorithms. Computationally it only requires 5-10% cost of STAP. The processor is tested using both the simulated and genuine airborne phased array radar data. With ample samples, its performance approaches optimum. In the case of reduced samples, it considerably outperforms STAP and others examined.

Download or read book Adaptive Phased Array Radar Signal Processing Using Photorefractive Crystals written by Kelvin Wagner and published by . This book was released on 1998 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers the development, test and evaluation of an adaptive phased array optical processor. This system is designed to optimally process the wide band signals from large phased array antennas in real time, achieving a computational throughput approaching 10 15 multiplies per second, demonstrating the potential of optical-based architectures to surpass performance achievable with conventional technology. The processor uses a three-dimensional volume hologram to create and store adaptive weights to simultaneously perform beam steering and jammer-nulling functions. The adaptive processor consists of two sub-sections, the main beam steering processor and the jammer-nulling processor. The nature of the architecture is that the number of processor components used is independent of the number of elements in the phased array. The report contains extensive treatment of models and analytical expressions developed to relate system parameters and to predict expected system behavior and performance of the experimental signal processors. A variety of jammer scenarios are described and analyzed. Experimental results obtained in a working hardware configuration of the processor are shown to verify the theoretical models. The models guided the development and evolution of the experimental optical hardware system with increasingly improved performance. By improving component stability, electronic gain, and feedback loop isolation, 45 dB jammer cancellation was demonstrated in the experimental system. Also described are results of main beam formation experiments that did not require a priori knowledge of the angle-of-arrival of the desired signal. In addition, results from simultaneous operation of both the nulling processor and the main beam processor are presented. The report contains extensive references and bibliography of the twenty technical papers published in con.

Download or read book Processing for Maximum Signal to clutter in AMTI Radars written by William Bernard Goggins and published by . This book was released on 1974 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phased array antennas and doppler signal processors designed to complement each other have been successfully used to maximize the signal-to-clutter (S/C) performance of AMTI radars. The optimum receiving antennas described in this paper allow for nonuniformities created in the ground-clutter doppler spectrum by the transmitting antenna and processing of the received doppler signal; the optimum signal-to-clutter digital processors allow for clutter spectra shaped by the combined effects of the transmitting-receiving antennas. The emphasis has been placed on producing antenna-processor designs that have complementary pass and reject bands. The mathematical techniques used in these designs maximize the ratio between the target signal and the clutter-plus-noise, expressed as a ratio of quadratic forms. The solution for the optimum design, which depends principally on the inversion of a single matrix rather than on any recursive technique, is obtained in closed form.
