Constant false alarm rate adaptive radar control

摘要

A method of analysing return signals of successive range cells in a scene using constant false alarm rate adaptive control comprising, for each successive range cell in turn: processing mathematically the return signal averaged over a predetermined number of cells near that cell, a first variable factor and the return signal for that cell, to derive a first resu adapting the first variable depending upon that first resu deriving a second variable factor in accordance with a predetermined relationship between the first and second factors; processing mathematically the second factor, the second averaged return signal and the return signal for the said cell, to derive a second resu and using the second result as an indication of the presence of an object of interest in the scene.
