摘要
提出利用海面浮动光电平台在波浪作用下的机动实现对空中目标定位与跟踪的方法。建立基于角度与角速度实现无源定位的数学模型,采用无迹卡尔曼滤波进行噪声干扰下的跟踪滤波,通过仿真分析了滤波算法在目标固定不动和目标匀速运动2种情况下的有效性。结果表明,对于含有零均值高斯噪声的角度和角速度测量数据,利用无迹卡尔曼滤波可以进行距离估算,并具有一定的精度和稳定性。
Passive ranging method for air target by floating optoelectronic platform which acts with the sea wave is proposed. The mathematical model of calculating the target range with the angel and angel variation rate is established, and unscented kalman filter is used for range estimation with noise interference. The effective of this algorithm is presented in both cases of target is fixed or moves in uniform motion. The results show that, as to the measurement data with zero-mean gauss noise, the accuracy and stability of estimated range can be improved by Unscented Kalman Filter.
