Hi, I am making Doppler effect based Radar sensor module. I want to measure the speed of a moving object. I have a sensor which gives a low voltage output signal(300 uV) with frequency 4320 Hz . This input goes to a preamplifier circuit and then to a microcontroller to detect speed of object. Can I get help on how to use the microcontroller for frequency detection and then speed measurement. Also what microcontroller from TI should I use for this purpose?
