Instead of using the homomorphic filter which is used to get rid of multiple noise and is a biased estimator, this algorithm translates speckle into locally stationary additive white noise.
该算法不同于有偏的去除乘性噪声的同态滤波算法,而是将噪声转化为局部平稳的加性白噪声。
Ultrasonic rang system is composed of ultrasonic receive-emit circuit, precise time measurement circuit and homomorphic deconvolution filter.
超声波测距系统主要由超声波的收发电路、精密时间测量电路、同态反卷积滤波器构成。
