Abstract

Conventional narrowband detectors suffer large losses in detection performance when the assumed sinusoidal receive signal is actually frequency modulated. Such would be the case for the detection of a maneuvering target by a passive sonar system. Based upon autoregressive spectral analysis a detector is presented which is nearly invariant to frequency modulation. The autoregressive detector is a CFAR receiver and requires less computation and storage than a conventional narrowband detector. Thus, the autoregressive detector should be an attractive complement to a conventional narrowband detector.
