Abstract

The paper proposes an adaptive system to reduce the spot jamming effects on radar operation. The proposed system is based on Kalman method for spectral estimation. The system has a short transient response. Consequently, it is suitable for radar waveforms that usually contain only a small number of samples. Simulation results have shown that the proposed system significantly reduces the spot jamming signal and enhances the desired signal. The effects of different factors, such as the filter order and the interference power are evaluated with the help of computer simulation.
