A policeman uses a radar operating at a frequency f = 24 GHz to detect the speed of incoming cars. The detection angle is set at 30 degrees. Find the frequency band of the low frequency bandpass filter to cover speed range from 50 km/hr to 200 km/hr.
How do i solve this??
how do i use the angle of detection here??
i think y can use the microstrip antenna as the sensor, and then y use monopulse system to solve the incoming angle problem,use the doppler frequency to detect radix velocity and then use the monopulse angle to solve the speed, the microstrip antenna's main aim is to solve the volume problem!
may be the "radar handbook " is useful to your project!
