ABSTRACT:
A false alarm control processor that receives sampled input radar video data and provides an output signal having a zero mean value. The processor accumulates the sample video for a range sweep of range bins, then stores the value and resets a counter. The stored value is scaled to form an estimate of the mean and subtracted from the input video signals of the following sweep. To prevent the mean from being biased by strong targets, a target exclusion function may be included to prevent accumulation of video from strong targets. However, if the noise or jamming level has increased for more range bins than a target would occupy, the video is then sampled by the accumulator so that the mean is responsive to changes in the level of the noise. Thus, the system provides a constant false alarm rate and accurate azimuth estimation in the azimuth integrator filter as well as allowing the azimuth integrator to operate with a relatively small dynamic range.
