摘要
提出了利用4个以上地面测量站,通过合理的布站,形成多目标测量系统,完成落区多目标子母弹测量,即同时测量目标至各站的距离,从而计算各目标在空中的位置。主要针对落区低抛子母弹地面平坦开阔,多径对测量的影响是主要因素,并采取适当的改善措施,以提高测距精度,通过对低抛子弹测量信道余量的估算,进一步说明有足够的信道余量,克服多径衰落。
More than four ground measurement stations are arranged reasonably to form a multi-target measurement system for completing the dropped-area multi-target cluster bombs measurement and the distance measurement from target to all stations, and calculating the air position of all targets. As the ground of dropped area is flat and wide,the effect of multipath propagation on measure- ment is the major factor. Aiming at this problem, some improvement measures should be adopted to improve the ranging accuracy. The estimation for low throw bullets measurement channel margin proves that the channel margin is enough to overcome muhipath fading
