Survey on modern radar signal processing

Abstract

The purpose of this thesis is to investigate the state of the art of radar signal design as well as radar signal processors and determine the actual trends in modern radar design. The use of a digital general purpose radar signal processor is discussed. The concepts of ambiguity and auto-correlation function are investigated in regard to radar resolution capabilities. the concept and analytical development of the DFT/FFT are presented. Quantization noise in a digital MTI processor and its effects in the improvement factor are analyzed. Optimization techniques for the response curve of digital MTI processors using staggered PRF are investigated. The SAR concept and analysis as well as techniques to obtain low correlator rates in the SAR digital processors are presented.
