Introduction:
This is used for simulating a Doppler shift up to a maximum frequency of 200KHz. This Doppler is first simulated on a carrier of 70 MHz and is fed to the next section and will be finally fed to a frequency of W-Band. The main scope of this simulator in to generate the doppler shift on a frequency range of w-band. athe implementation of doppler shift is first achieved on 70 MHz carrier generated using the digital board. This 70 MHz IF is then will be up-converted to W-Band to achieve the doppler shift
