Most forward-facing radar sensors operate between 77 and 81 GHz which is 77 to 81 billion times a second. The primary use for this range is because of the environment this sensor is operating in. Radar sensors typically have fewer transmitting antennas than receivers (Figure 6). Antennas are arranged in an array with known distances from each other. This is part of the mathematical equations scientists have been able to exploit to gather information about the environment around the vehicle. Simply put, the flat board radar antennas are mounted to emit radiation chirps in a cone-like fashion and the receiving antennas pick up the reflected chirps. The system calculates the distance via timeof-flight the same way cameras do. As far as the azimuth location, the sensor performs quite a bit of work to accomplish this.
