  • Patent number: 4025919
    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 certain predetermined parameters. On the basis of values of these parameters a probability code is developed which is a measure of the probability that a target is present. The signal which is divided into a corresponding number of range cells, is rewarded if a target like signal occurs within a certain number of resolution cells of the same range on the next signal. If no target like features are present in this zone on the next signal, a penalty is applied.
