摘　　要：为了适应现代战争的需求,排除干扰,分离相互交叠的目标,提出了一种多目标识别的新方法。分析了各种干扰产生的原因,利用和差比以及信号脉冲前后沿的幅度差对重叠信号进行解码,并采用单脉冲测角技术精确地得到各目标的角度,最后采用点迹相关技术对多次询问的信号进行进一步的处理,最终得到每个目标的航迹。实际应用验证了该方法的有效性。For meeting the requirement of modem war, avoiding interference and separating cross multi - target, a novel multi - target identification method is proposed. After analysing the cause of all kinds of interference, overlap signals are decoded with sun - minus ratio and amplitude discrepancy of forward - edge and backward - edge of signals pulse. Angle of each target is obtained accurately by single pulse angle - measurement technique. Finally, path of each target is gained by processing signals of multi - inquiring based on the technique of point track correlation. Engineering application has proven the effectiveness of this method.
