On the hardware, a TV signal power low altitude radiation detection system was designed based on UAV to measure the frequency and power of TV signal. On the software, a power path loss compensation algorithm of TV signal was developed to filter, calculate, store and display the data. Compared with the traditional method, the TV signal power of the new system in Zhengzhou and Shijiazhuang was tested and validated. Results show that, the measure error of the proposed method is 5 dB less than that of the traditional ground radiation detection system. The new method can effectively solve the problem of ground detection and location, reduce the detection error caused by complex environment and equipment defects, and improve the detection efficiency and accuracy. | | 查看全文查看/发表评论下载PDF阅读器 | |
