For purpose of improving the effective transmitted power of radar jammer, this paper discusses the relationship between the jamming power and the interference signal waveforms in Radar ECM system, and analyzes the significance of enhancing transmitter jamming power by improving the interference waveform. Referencing the ideas of improving PAPR of communication signals, we put forward the methods for improving PAPR of radar jamming signals, analyze the effect of five improving methods including the constant envelope jamming waveforms and others by the experimental data simulation, and finally compare their advantages and disadvantages as well as the applied range. The research results obtained have important instructive significance on the engineering design.
