摘要
针对线阵CCD三角定距系统在定距区域内随着距离增大定距精度下降,导致激光引信定距距离超差,通过对定距误差来源分析和半实物仿真结果分析,提出在小基线条件下采用加权平均算法求解目标位置,以此提升线阵CCD三角定距区域内远端的定距精度。测试结果表明:对比传统的波形中心法,采用加权平均法的线阵CCD激光近炸引信可有效提高定距精度。
For the problem of the more far the less accurate can get in the range of Linear CCD triangle ranging,which leads to the out-of-tolerance of the laser fuze setting distance,the weighted average algorithm was used to solve the target position under the condition of short baseline,by analyzing the source of range error and the result of semi-physical simulation,so as to improve the distance accuracy of the remote end in the linear CCD triangle ranging region.Experimental verification shows that compared with the traditional waveform center method,weighted average algorithm can effectively improve the ranging accuracy of Linear CCD triangle ranging lazer fuze.
