Determination of character of the interactions of signals response in nonlinear radar

The problem of determination of combined response signal (RS) from the obstacle nonlinear scatterers (NS) by a special system of preliminary nonlinear sounding (SPNS) in nonlinear radar is examined. The investigation of interaction of the components of combined RS from the obstacle NS, which arbitrarily spread in space and have different scattering capability is done. It is shown that for the definition with certain confidence probability the character of the components interactions of combined RS from the obstacle NS, its necessary jointly to analyze the efficiency of exposure the receiving response signals by three methods - χ²-test, coordinated processing of signals and "max-λ" test.
