Abstract
A radar system includes transmitters and receivers configured for installation and use in a vehicle. The transmitters transmit radio signals. The receivers receive radio signals that include the transmitted radio signals reflected from objects in an environment. Each receiver has an RF front end, an analog-to-digital converter (ADC), a digital signal processor, and a controller. The digital signal processor processes the data from the ADC and stores data samples in a buffer. The buffer operates in several modes defined by the controller. These modes include replay mode, loopback mode, quiet mode, and throttle mode. By controlling the buffer, the same received samples can be processed in multiple ways to generate information on targets at different ranges and velocities. The buffer is read out and the data is processed further to enable the radar system to determine range, velocity, and angle of targets in the environment.
