Paper Abstract

This paper reviews the relation between the radar ambiguity function and the matched filter, then introduces a geometric concept of the matched filter as a slice of the ambiguity function along a frequency-shift line. With the help of the geometric concept, the conventional matched filter can be generalized to a time-varying filter, which is equivalent to the optimum time-frequency correlator and can be implemented with wavelet transforms. The application of the optimum wavelet correlator to inverse synthetic aperture radar (ISAR) will be illustrated.
