A noise FM-CW radar signal possesses a ‘thumbtack’ average ambiguity function (AAF). The authors present a spectral analysis of the echo signal, and describe two alternative types of signal processing, based on spectral comparison techniques. The two approaches provide a radar that either produces an output when a target is present inside a chosen range, or when it is present between two chosen ranges (giving a zero range ‘hole’ characteristic). The noise FM-CW system has inherently good ECCM properties.
