1. A radar signal digital processor which suppresses clutter disturbances and enhances useful signals of given Doppler frequency, comprising:
- a finite impulse response filter (10);
an estimator of disturbance parameters (4);
a memory (5) coupled to an output of the estimator (4);
a weight synthesizer (8) coupled to a second output of the estimator (4) for calculating complex weights; and
a register (9) for storing the complex weights for output to the finite impulse response filter (10).

Abstract
A digital processor for radar signals which can perform adaptive suppression of the disturbance clutter and enhancement of the useful signal of given Doppler frequency. It can approximate the principle of operation of the optimum processor, which is that processor which maximizes the signal-to-noise ratio. Such processor can also cancel, in a adaptive manner, a clutter component having an approximately Gaussian power spectrum.
