Abstract

Abstract: The present wideband digital beamforming method has some disadvantages in engineering application of radar jamming, such as single applicable signal, poor jamming effect and high implementation difficulty. A wideband digital beamforming method for radar jamming based on second-order cone programming (SOCP) theory is adopted. The amplitude and phase of wideband jamming signal are modulated using a corresponding wideband finite impulse response filter in each channel of beamformer. In order to obtain the best filter coefficient, a linear constrained minimum power criterion is adopted to design and optimize the beamformer. The optimization difficulty is reduced by eliminating the frequency dependence of side lobe constraint and transforming the analytical form of filter coefficient solution into the corresponding SOCP form. The simulated results show that the proposed approach can be used to solve the optimal design issue. Key
