How do l detect the velocity and range of an object using 10.525GHz microwave doppler sensor with arduino uno?

I did not use doppler sensor with arduino, but i have used Ultrasonic sensor & in ultrasonic sensor we have to define Trig & Echo pins first ,i.e Ultrasonic ultra1(26,27)

& then in void loop we call it using ultra1.Ranging('CM'). Same procedure may be used for doppler sensor after adding its library.

this would be helpful
