The optimal parameters of a two channel canseller of interfering emission

Abstract

The task of optimizing of the compensators of interfering radiations in radars with fast linear scanning is relevant. The main problem of autocompensators with a gradient self-tuning method is the large dynamic errors in the formation of weight coefficients. To reduce the impact of dynamic errors on compensation efficiency, the bandwidth extension of closed self-tuning circuits is used. However, in this case, the contribution of fluctuation errors to the total errors increases. There are optimal values of autocompensator parameters, at which the total errors are minimal. The article obtained expressions for the optimal parameters of a dualchannel auto-compensator for interfering radiations with a gradient self-tuning method when suppressing the signals of two radiation sources. For simplicity, the case of self-tuning chains with the first order of astatism is considered, and the side lobes of the main radiation pattern are described by harmonic approximation. The obtained results are confirmed by the simulation modeling of a two-channel auto-compensator.
