Programmable FFT Linear FM Waveform Processor. Phases II and III.

Abstract

The PWP program, Programmable Fast Fourier Transform Linear FM Waveform Processor, features three principal developments: the step transform processing algorithm, floating point FFT processing and CMOS/SOS LSI technology. The step transform algorithm was studied and its realizability demonstrated under a pulse compression techniques study program(1) (F33615-72-C-1634). It features a sub-aperture processing technique for the digital pulse compression and expansion of linear FM waveforms. The algorithm was extended to sub-array processing of synthetic aperture radar (SAR) in Phase I of the PWP development program(2) (F33615-73-C-1275). Both SAR azimuth focusing and linear FM pulse compression can be processed with the same hardware configuration. The objective of the hardware development effort was to construct a programmable pulse compression/expansion system for use in advanced linear FM radar and synthetic aperture processing applications.
