The Sultan Qaboos road is designed to operate at a speed of 100Kmph, but some people are racing above the limit and some people are trailing below 80Kmph, and cause multiple incidents on road. Design a radar frequency so that detect the both the speeds that is below 70kmph, and above 110kmph, provided the PRF is 500Hz only. The radar should not be blind between the above specified velocities and it should detect both the speed accurately.(Explain your assumptions of the radar and their specifications clearly, so that which radar frequency can be readily used on site)

A frequency-modulated continuous-wave radar is extensively used for traffic data collection. It conveys a continuous-wave signal. And then compare the frequency difference between the conveyed signal and reflected signals to estimate the vehicle range and its speed.
Let radar is installed at the roadside with a squint angle. Then the Doppler frequency coming from the moving vehicle is intensify compared with that from the perpendicular vehicle detector.
The radar frequency expression is given as:
