description 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.
