摘    要:本文提出了一种电视信号功率辐射检测新方法,用于对电视信号发射系统发射端EIRP进行检测.在硬件上,根据该方法搭建了以无人机为平台的电视信号功率低空辐射检测系统,对电视信号频率和功率进行测量;在软件上设计了电视信号功率路径损耗补偿算法,对数据进行筛选、计算、存储和显示.系统在郑州和石家庄的电视信号塔上的电视信号功率对实际台站进行了测试验证,结果表明,该方法比传统地面辐射检测的测量误差减小5 dB以上,有效地解决了地面检测选址困难的问题,降低了由于复杂环境、设备缺陷带来的检测误差,提高了检测效率和准确性. 

关 键 词:电视信号  无人机  功率辐射检测  信号路径修正算法

Abstract:In this paper, a novel method of television signal power radiation detection was presented to detect the equivalent isotropically radiated power (EIRP) of TV transmitting end. 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.
Keywords:TV signal  unmanned aeniad vehicle  power radiation detection  signal path correction algorithm
