Stretch-processed LFM waveforms are in use in many high-resolution applications such as SAR and ISAR. New processing configurations are being considered that would link multiple LFM radars in a distributed architecture. It is important to understand the interference effects of LFM waveforms, particularly with regard to frequency. This chapter introduces interference regions in range-frequency space as a tool for characterizing LFM interference in a distributed environment.
