Phase-Coded Waveforms and Their Design The role of the ambiguity function

With the advances in radar hardware, computational algorithms, and coding schemes, the area of waveform design in radars enjoys continued attention. All these advances have produced creative, synergistic impact on the design of radar waveforms, as well as provide improved ambiguity function and target detection properties. However, short duration pulses are required for good range resolution in the design of radar waveforms as well as the detection of sufficient energy on target. A given waveform is designed by the use of constant amplitude (CA) sequences with zero autocorrelation (ZAC).
