| 摘 要： | 为改进三元阵被动测距性能,采用了滑动窗互相关器估计代替常规的互相关器测时延,与常规互相关器相比时延计性能明显提高,当常规的互相器无法测得相关峰时,滑动窗互相关器仍然能较准确地测得时延;采用的适用于近程的方位和距离的改进计算公式,在近程有很高的精度.利用浅海、近程的三元阵被动测距海试数据,对所采用的改进方法进行了验证,目标船为摩托艇,将测距结果与精度为20 cm的差分GPS定位结果比较,表明二者吻合较好,相对误差在米量级.

| Abstract: | To improve passive ranging of three-sensor arrays,a sliding correlator was adopted to improve the performance of time delay estimation.Compared with the traditional correlator,the sliding correlator's abilities are substantially increased.The sliding correlator gets time delay clearly,while the traditional correlator cannot even distinguish the correlating peak.An improved formula with high precision for near targets was adopted.The experimental results of a three-sensor array's near field passive ranging i... |
