An adaptive radar signal processor is operable to effectively suppress clutters and extract a target signal with a high degree of accuracy and includes a memory storing two-dimensional radar data corresponding to range and azimuthal directions, multipliers multiplying each of data of the same range but different azimuthal direction read out from the memory, an adder generating the added data of the multipliers as an estimated data, and a weighting coefficient determinater which determines the optimum weighting coefficients based upon the stored radar data so that the difference between the radar data and the estimated data at an observing position is minimized, and produces the difference data as a clutter-suppressed radar data.

An adaptive radar apparatus comprising: a memory for storing radar data in a time sequence; means for reading out the radar data from the same range in response to a plurality of transmission pulses; a plurality of multipliers for multiplying each of a plurality of data read out from said memory by a predetermined weighting coefficient; an adder for adding the outputs of said multipliers and generating the added data as an estimated data relative to an observing position; weighting coefficient determination means for determining the weighting coefficients based upon said stored radar data necessary for the optimal estimation of the data at said observing position so that the difference between the radar data and the estimated data at said observing position is minimized; and means for producing the difference between the radar data and the estimated data obtained from said adder as a clutter-suppressed radar signal.
