MARTIME RADAR DETECTION PERFROMANCE OF FAST AND SLOW SCAN RADARS USING FREQUENCY AGILITY

The relative detection performance of fast scan and slow scan radars utilizingfrequency agile waveform transmission is examined. A real, wide bandwidth, sea clutter data set is compressed using a set of contiguous narrowband compression filters to create data sets corresponding to three or ten frequency steps. Both a non-coherent and coherent Kelly detection scheme are implemented and tested. A detection performance advantage is demonstrated for the fast scan configuration for both frequency agile sets under coherent Kelly detection. The non-coherent detector case is less clear-cut with a superior fast scan performance noted for the three frequency agile set but equivalent performance noted for both fast and slow scan rates with the 10 frequency agile set.
