摘要
简要介绍了超分辨算法实现测高的基本原理,以及采用超分辨算法开展的米波雷达测高试验情况,给出了若干淡水反射面条件下的外场试验数据。试验统计结果表明:在满足一定信噪比的条件下,采用空间平滑+最大似然超分辨处理法可有效提高米波雷达在低仰角的测高精度。
The principle of angle super-resolution algorithm, briefs the height-measuring trial research of meter-wave radar in VHF band, and gives some outfield experimental data on the signal reflection from freshwater surface. The statistical results from the experience indicate that, in the condition of some signal-to-noise ratios (SNR) , the maximum likelihood method with spatial smoothing algorithm can effectively improve the altitude precision in low elevation angle of meter-wave radar.
