Multi-Period Ambiguity Function of LFMCW Radar Signal

The multi-period ambiguity function of LFMCW radar signal is given, and compared with single-period ambiguity function. Some properties of difference with single-period is discussed, these properties include the multiple-single period PAF,cut along the principal axes and volume limitation. The computer simulation showed that Doppler resolution being higher, but delay resolution is not improved as number of periods increases.
