【摘要】：高频地波雷达对海上目标跟踪探测时,由于距离和方位角分辨率低且受到随机噪声的干扰,导致对目标位置探测不准确,形成的航迹会偏离目标的真实位置,影响跟踪的准确性。针对这个问题,结合海上特定目标跟踪的实际,本文从航迹的角度出发,基于对距离和方位角误差时间序列的统计建模,提出了一种基于同步船舶自动识别系统(Automatic Identification System,AIS)信息的高频地波雷达海上目标航迹校正方法。在高频地波雷达与AIS同步跟踪期间,采用统计回归的方法建立目标距离和方位角误差的校正模型;在高频地波雷达独立跟踪时,利用得到的模型分别对距离和方位角进行校正。利用实测高频地波雷达目标探测数据进行了航迹校正实验,校正后距离和方位角的均方根误差分别减少了约90%和75%,航迹跟踪效果得到了显著改善。
[Abstract]:When high frequency ground wave radar detects targets at sea, because of the low resolution of range and azimuth and the interference of random noise, the detection of target position is inaccurate, and the track will deviate from the real position of the target. Affects the accuracy of tracking. In view of this problem, combined with the practice of specific target tracking at sea, this paper presents a synchronous ship automatic identification system (Automatic Identification System,) based on the statistical modeling of distance and azimuth error time series from the point of view of track. AIS) method for track correction of high frequency ground wave radar targets at sea. The calibration model of target distance and azimuth error is established by statistical regression method during the synchronous tracking between HF ground wave radar and AIS, and the range and azimuth angle are corrected by the obtained model in the independent tracking of HF ground wave radar. Track correction experiments are carried out using the measured target detection data of HF ground wave radar. The RMS errors of range and azimuth are reduced by about 90% and 75% respectively after correction, and the track tracking effect is improved significantly.
