It also provides a method for correcting the determing target track deflection which is caused by the underwater platform inclination an swing due to water flow, which is simplyfied when the underwater platform inclination is not great, The data obtained from oceanic experiments are applied to do simulation proofs.
给出了非固定水下平台对水面目标航迹的确定方法，提供了一种方 法修正平台倾斜和旋转对确定目标航迹带来的影响，并在平台倾斜不大时进行了简化，最后利用仿真数据进行了仿真验证。
2.
Serious biases in both the long-range detection and accurate location track, may be caused by the rocking of underwater platform in the complicated ocean current and tide, and may become great barricades on target detection, identification and classification.
水下平台由于处于海流、潮汐之中，引起平台自身的晃动与扰动，导致平台在远程探测、精确定位跟踪中产生严重偏离，对探测系统进行目标探测、识别、分类等工作形成障碍。
