摘要： A target extractor for radar systems which accurately determines the radial position of the target within the range cell containing the target. The azimuth of the target is determined by conventional extractor systems. An incremental target range is located with respect to a primary range cell boundary. The primary range cell is selected as the range cell which contains the maximum number of reflected transmitter pulses. The number of reflected transmitter pulses received in secondary range cells located radially below and radially above the primary range cell is determined by the target extractor. The target extractor also determines the ratio of the pulses detected in the secondary range cells which are located radially on each side of the primary range cell. The location of the target defined within the radial dimension of the primary range cell is determined by interpolation circuitry in the target extractor. The interpolation circuitry shifts the effective location of its output signal by an amount which is proportional to the determined ratio of the pulses in the secondary range cells.
