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 a controller, a buffer, and a post-buffer processor. The receiver processes the received radio signals and stored data samples in the buffer. The buffer operates in a plurality of modes defined by the controller. Two or more modes of operation of the plurality of modes are performed with a same set of data samples stored in the buffer. The post-buffer processor receives data samples from the buffer and performs at least one of correlation processing to determine object ranges, Doppler processing to determine object velocity, and, in combination with other receivers of the plurality of receivers, further processing to determine angular locations of the objects.
