A method and apparatus is provided. The apparatus a processor configured to generate a first square wave, generate a second square wave, wherein the first square wave and the second square wave are driven by a reference frequency oscillator, modulate a radio frequency wave with the first square wave, downconvert the modulated radio frequency wave to an intermediate frequency, filter the downconverted modulated radio frequency wave, convert the filtered downconverted modulated radio frequency wave to a digital signal, and integrate the digital signal. 提供了种方法和设备。该设备包括处理器，该处理器配置为生成第方波；生成第二方波，其中，第方波和第二方波由参考频率振荡器驱动；利用第方波对射频波进行调制；将调制的射频波降频转换为中频；对降频转换的调制的射频波进行滤波；将滤波的降频转换的调制的射频波转换为数字信号；以及对数字信号进行积分。
