Pulsed FMCW waveform design for LPI radars based on stretch processing

Abstract

An FMCW radar waveform design based on stretch procesing is described. Transmit (TX) and Receive (RX) functions are separated in time. A single antenna with no isolation problems can be used. A rigorous analysis of coherent processing is presented. Advantages and disadvantages are discussed. Compared to Pulsed Doppler Radar (PDR) this waveform has significant LPI properties. A generic design example is also given. © 2012 EUROPEAN MICROWAVE ASSOC
