Waveform design for optimized ambiguity response

摘要

This is a method of waveform design and range correlator implementation t uses weighting to optimize a radar receiver's ambiguity response in both the temporal and frequency dimensions of the ambiguity function. It is an extension of group-complementary code structure and is based on a multipulse processing technique.PPThe procedure minimizes frequency sidelobes over a selected interval in the spectral domain between dc and the pulse repetition frequency and completely eliminates temporal sidelobes throughout the pulse repetition interval. It minimizes clutter and multitarget interference in an active- sensor target acquisition and tracking application, and still allows weighting of the pulse responses to reduce frequency domain sidelobes.
