项目摘要
Outdoor experiments were conducted to detect the torrential rain from the signal of LCX(Leaky Coaxial Cables). The received signal was contaminated by high-frequency and high-intensity noise, thus, we removed the high frequency components using discrete wavelet transform, and could extract the low frequency components of the discontinuous points due to the heavy rain. Because the discontinuous points originating in external noise were also extracted simultaneously, we built an algorism which eliminatesunnecessary discontinuous points. The algorithm(Unnecessary Discontinuous Point Exclusion Algorithm) consists of three steps ; 1)"Detection of the large impulsive noise by the threshold-judge of the signal-fluctuation", 2)"Detection of the edges of the continuous noise by the Lipschitz-Holder index", and 3)"Detection of the small impulsive noise by the test of outliers using percentile". As a result of applying the algorithm to the signal-fluctuation, it was shown that heavy rain with 1 min rainfall intensity greater than 30mm/h is detectable.
利用泄漏同轴电缆(LCX)信号进行了暴雨探测的室外实验。由于接收信号中含有高频、高强度的噪声,利用离散小波变换去除高频成分,提取暴雨间断点的低频成分。由于同时也提取了来自外部噪声的间断点,因此我们建立了一种算法,消除了不必要的间断点。该算法(不必要间断点排除算法)包括三个步骤:1)“通过信号波动的阈值判断检测大脉冲噪声”,2)“通过Lipschitz-Holder指数检测连续噪声的边缘”,3)“通过使用百分位数的异常值检验检测小脉冲噪声”。将该算法应用于信号起伏的结果表明,1 min雨强大于30 mm/h的暴雨是可检测的。
