DF Device Protection Against Coherent Noice Effects to Solve Problems of Air Space Safety Ensuring
A direction-finding of object represented as a complex system of sources of radiation in the presence of radiation sources of coherent noise is a technical challenge. Application of the modified Prony method that uses a parametric exponential model of the analyzed signal allows obtaining estimates of bearing geometric center of located object in a coherent gamming. The results of simulation of the process of direction finding system consisting of two sources of coherent radiation source, supplemented with the equivalent background radiation, demonstrating the efficiency of the proposed method are adduced.
