An accumulated statistics CFAR method and device operates using integrated data to maximize the probability of target detection for a given false alarm rate. The CFAR hardware varies its detection criteria as a function of the statistics of the range gate in question. The detection threshold is based on other range gates seen in the past which contain the same terrain type.

A moving target detector comprising: extraction means for extracting filter bank output values from an input to generate an environmental condition, said environmental condition being a function of said filter bank output amplitudes, said environmental condition representing at least a subset of a memory address; memory means for storing a plurality of threshold values, said memory means coupled to said extraction means to receive said at least a subset of said memory address; comparator means, said memory means coupled to said comparator means to relay a threshold value stored in a memory location addressed by said at least a subset of said memory address; comparator means receiving said filter bank output values and comparing said threshold value with a value from said filter bank output values; and said comparator means outputting a target detect signal if said value from said filter bank output values are greater than said threshold value.
