摘要:

针对雷达探测威力预报中海表温度测量问题，提出一种基于红外传感器的修正方法.分析了红外传感器产生测量偏差的原因，通过对海面红外辐射及反射情况进行建模，仿真分析了天空温度对海表面温度测量结果和雷达威力预报结果的影响，并提出海表温度的修正方法.实验结果表明，将该方法应用到雷达威力预报中，预报结果与实际雷达威力相对误差小于20%的概率高达80%，显著提高了雷达威力预测预报精度.

Abstract:

Aiming at the problem of sea surface temperature (SST) measurement in radar power prediction (RPP), a modification method of sea surface temperature is proposed based on infrared sensor. The measured deviation of infrared sensor for SST is analyzed. The infrared models of sea surface radiation and reflection are modeled. The affections of sky radiation to result of SST and RPP are analyzed by simulation. A modification method for RPP is deduced. Through experiment, the result shows that the relative error of prediction result is limited in 20% with 80% probability by this method, which greatly enhances the prediction accuracy.
