| 摘要: |
| 针对弹载雷达波形易受末制导过程中转发干扰影响的问题，提出了一种基于频移键控（FSK）和相移键控（PSK）复合调制的抗干扰波形优化算法。分析了FSK-PSK复合调制信号的模型函数，在转发干扰模型基础上构建了脉内切片转发式干扰抑制模型，基于子脉冲正交性设计了基于交替方向乘子法（ADMM）的脉内PSK调制优化算法。仿真结果表明，与PSK信号相比，调制优化的FSK-PSK信号脉内子脉冲正交性提升约10 dB，能够有效抑制脉内转发干扰。 |

| Abstract: |
| Aiming at the waveform of missile borne radar is simple and easy to be affected by the repeater jamming in the terminal guidance, an anti-jamming waveform optimization algorithm based on the frequency shift keying(FSK) and phase shift keying(PSK) composite modulation is proposed. The model function of FSK-PSK composite modulation signal is analyzed. Based on the orthogonality of sub pulses, an optimization algorithm of intra pulse PSK modulation based on the alternating direction multiplier method(ADMM) is designed. The simulation results show that comparing with PSK signal, the intra pulse sub pulse orthogonality of FSK-PSK signal optimized by modulation is improved by about 10 dB, which can effectively suppress the intra pulse forwarding interference. |
