ABSTRACT:
Apparatus which automatically detects targets of interest in line scanned amplitude modulated data systems such as side scan radar or sonar. The apparatus examines a received signal for target highlights followed by a target shadow of a certain length, depending upon range. The apparatus indicates the presence of a target of interest when the highlight-shadow information is contained in multiple sequential signals over a predetermined range window.
