摘要:
针对连续波调频、随机脉位调制单一体制引信信号及脉冲型复合信号无法兼顾分辨力、抗干扰能力和引信实时性的问题,提出了脉位编码与线性调频复合调制引信信号。利用Costas序列良好的模糊特性和抗干扰特性重构了一种新的脉冲位置编码方式,结合波形选择法,构造了脉位编码与线性调频复合调制引信信号。仿真结果表明,该复合调制引信信号在参数选择合理的情况下能够保持线性调频信号良好的距离、速度分辨力,无需若干样本积累即拥有一定的伪随机特征,在一定距离和速度范围内,固有抗干扰能力优于线性调频信号,可应用于工程实践。
Abstract:
Aiming at the problem that the single system CW FM fuze signal of random pulse position modulation and pulsed compound signal can not give consideration to the resolution, anti-jamming ability and real-time at the same time. To solve the problem, the pulse position coding and LFM compound modulation fuze signal was proposed. A new pulse position coding method was reconstructed by using the good fuzzy and anti-jamming characteristics of Costas sequence. Combined with the waveform selection method, the pulse position coding and LFM compound modulation fuze signal was constructed. The simulation results showed that the compound modulation fuze signal could maintain good range and speed resolution of LFM signal without some sample accumulation, and had certain pseudo-random characteristics. In a certain range and speed, the intrinsic anti-jamming ability was better than LFM signal.
