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 CMOSSOS LSI technology. The step transform algorithm was studied and its realizability demonstrated under a pulse compression techniques study program1 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 program2 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 compressionexpansion system for use in advanced linear FM radar and synthetic aperture processing applications.
