Phase-Coded Waveforms and Range Superresolution

Abstract

Phase-coded pulse-compression waveforms have been investigated for compatibility with superresolution processing techniques in the range domain. Two waveforms were tested via simulated data; a binary Barker code, and a quadriphase code. The binary code was not compatible and did not permit resolution finer than the conventional matched filter. The quadriphase code, on the other hand, was found to be partially compatible and permitted accurate resolution/location of one or two point targets within a rangebin. However, it could not handle more than two closely spaced targets because of its inherent limitation of two degrees-of-freedom (for superresolution processing purposes). Therefore, these phase-coded waveforms are not recommended for high resolution processing in range. The processor burden would not be cost effective for the limited benefits available.
