旋转调谐磁控管捷变频雷达频率预测方法

摘要

In order to predict the frequency of the frequency-agile radar of rotary-tuned magnetron,the transition vector of frequency variation trend is defined.Then,the nonlinear equation set for estimating the tuning parameters are transformed into linear equation set.Finally,a frequency prediction method based on the least squares estimation is proposed.Compared with the existing methods,the proposed method has lower requirements on the data quality,and is more adaptive to the complicated application environment.Experiment results based on the measured data indicate the effectiveness of the proposed approach.%针对旋转调谐磁控管捷变频雷达的频率预测问题,定义了频率变化趋势转折向量,在此基础上将调谐参数估计的非线性方程组转化为线性方程组,提出了基于调谐参数最小二乘估计的频率预测方法.相较于已有工作,所提方法放松了对数据采集质量的要求,具有更强的适应复杂应用环境的能力.实测数据测试结果验证了所提方法的有效性.
