Patent ID: 8760340

Claim:
An apparatus comprising: a plurality of range matched filters configured to: receive a plurality of radar return signals detected by an antenna; and range match filter the radar return signals to place the radar return signals into a plurality of range cells, where the plurality of range cells are the size of a target plus a target range motion during an integration time, the target being an object of interest associated with at least one of the plurality of radar return signals; a Doppler-acceleration matched filter system configured to Doppler-acceleration process the radar return signals in the range cells to facilitate identification of one or more targets; a sliding window integrator (SWI) configured to improve a monopulse-based azimuth angle accuracy, which is based on a signal-to-noise ratio of a single radar return pulse of the plurality of radar return signals, by integrating the radar return signals; an inverse filter system configured to perform azimuth processing by azimuth match filtering the radar return signals to divide the radar return data into azimuth cells, wherein each azimuth cell represents a slice of an azimuth bandwidth of the radar return signals; and an adaptive threshold device configured to determine a strength of the radar return signals and subject the radar return signals to a threshold criteria to identify one or more targets.
