| 摘 要： | 通过对某155 mm炮射高动态旋转榴弹飞行动态应力变化规律及其对接收机基带信号处理的影响分析,提出一种适用于此类特殊环境下的高动态接收机环路跟踪策略. 从接收机环路跟踪性能角度出发,分析不同跟踪环路信号跟踪性能随噪声带宽变化规律,为合理选取噪声带宽提供理论依据. 实验表明,改进后环路设计方案不仅能较好地实现对弹道的检测,同时显著改善了检测信号的信噪比,提高了接收机的跟踪性能和抗干扰能力.

| Abstract: | Taking a 155 mm missile-borne grenade as representative and analyzing its special projectile flight dynamic stress variation and its effect on the receiver signal processing, a high dynamic receiver tracking loop strategy was put forward to adapt the special environment. Combined with the loop tracking performance theory and analyzing the tracking performance changes with the noise bandwidth of different signal tracking loop, a theoretical basis was provided for the reasonable selection of noise bandwidth. Simulation results show that, the improved design scheme can not only detect the trajectory, but also improve the detection signal to noise, which enhance the tracking performance of the receiver and the anti-interference ability. |
