Abstract
For the disadvantage that piecewise random shift frequency jamming cannot generate deception to target speed,a jamming method based on phase sectionalized modulation is proposed for linear frequency modulation(LFM) pulse compression radars.Its basic principle is introduced,and the jamming signal's mathematical model is established.Then the magnitude-phase characteristics and pulse compression result of jamming signal are derived,and the impacts of number of signals,modulation phase and phase modulation value on overspread effect are analyzed.Simulation results show that the method can achieve reliable jamming effects and has higher jamming power utilization compared with piecewise random shift frequency jamming.关键词
