一种三坐标相控阵雷达的TWS算法

根据某三坐标相控阵雷达工作的特点，本文设计了一种Tws算法。该算法针对相控阵雷达变扫描周期的特点进行了适应性处理，针对不同目标模型状态变量不一致的问题进行了统一化的处理，并且在交互多模型算法中根据模型匹配程度动态调整模型的噪声协方差以达到更好的跟踪效果。该算法在雷达的实际跟踪试验中，取得了预期的效果。

TWS Algorithm of 3-D Phased Array Radar

In the paper, TWS algorithm is presented in terms of the characteristics of a 3-D phased array radar. The algorithm has been made adaptive process based on the characteristics of phased array radar＇s variable scan period. The algorithm is also used to settle the problem of inconsistent variable dimensions of different target models, as well as dynamically adjust the covariance matrix of noise to get a better capability of tracking based on to the match level between moving model and system model in the IMM algorithm. Expected achievement has been made in real radar tracking experiment.
