摘要
针对单脉冲雷达上存在的测量误差进行了详细的研究和分析,通过与单脉冲测量雷达数据的误差模型进行比较,并给出了比较的图形,判断出系统产生误差的原因,通过采取四象限比较法总结出了系统误差出现的规律,并由此推导出系统误差模型,从而实现了对系统误差进行有效的修正;同时运用自适应卡尔曼滤波的方法抑制了随机噪声,从而提高了雷达测量数据的处理精度,这一方法在实际应用中证明是行之有效的,并且取得了良好的效果。
By reseaching and analysing the measure error in monopulse radar and comparing with error model of radar data measurement used monopulse, the reason of sestem error is estimated. The system error is corrected efficaciously by system error model which is educed by summarizing error rule of system with four quadrant comparation method. It decreases the random noises by using adaptive Kalman filtering algorithm, advances the processing precision of radar datas and makes a good effect in practice application.
