A new chirp-coded radar waveform

A new chirp-coded radar waveform (ICC-2) is introduced, relative to the old type intra-pulse chirp-coded (ICC-1) waveform described by Xu Qing (Syst. Eng. and Elect., vol.12, p.7-8, 2000). The waveform forming, ambiguity function and match filter output are discussed. From the discussion, it is found that the ICC-1 can achieve higher resolution than chirp and phased code waveforms and ICC-2 is not suitable for target position radar. The reasons are given by analyzing the spectrum, ambiguity function and match filter output. Finally, it is indicated that through some restructuring, ICC-2 can achieve good performance by stepping frequency etc. It is useful in radar target identification applications.
