摘　　要：提出一种应用于无线电近炸引信的非对称三角波线性调频多普勒体制近程探测方法。利用非对称三角波线性调频信号上升段和下降段调制斜率的不同,使引信差频段仅使用一个固定频点的窄频率通道即可结合数字信号处理算法对两个不同距离的运动目标回波进行同时定距监测,并利用多个不同参数的三角波调制波形串联等效实现多点连续测距,能够简化引信硬件电路和数字信号处理算法复杂度。通过缩窄差频段电磁耦合通道入口频带宽度提升引信抗电磁干扰能力,通过降低采样率及简化硬件降低引信设计制造成本。通过理论分析及数字仿真对该方法的正确性进行了验证,通过依据该方法研制的引信探测样机进行推靶和靶场炮射存储试验,验证了该方法的有效性和工程可实现性。A novel detection method based on asymmetric triangular wave linear FM Doppler system for proximity fuze was proposed.By utilizing the different modulation slopes of the ascending and descending segments,the echoes of moving targets at different distances could be monitored at the same time in a narrow band IF frequency channel at a fixed frequency.The proposed method could also be combined with digital signal processing algorithms to achieve multi-point continuous distance measurement using multiple triangular modulated waveforms connected in series.The method could greatly simplify the hardware circuit while reduce computational complexity,and cost of design and manufacturing was reduced.By narrowing the electromagnetic coupling bandwidth,the antijam capability was enhanced.The correctness and reasonableness of this method was proved by mathematical analysis and simulation.Engineering realizability was verified by prototype of fuze developed according to this method through moving targets and gunshot test.
