Abstract
A radar includes transmitters, receivers, a memory, and a processor. The transmitters transmit radio signals, and the receivers receive reflected radio signals. The processor produces samples by correlating reflected radio signals with time-delayed replicas of transmitted radio signals. The processor stores this information as a first data structure, with information related to signals reflected from objects as a function of time (one dimension of the data structure) at various distances (a second dimension of the data structure) for various receivers (a third dimension of the data structure). The first data structure is processed to compute velocity and angle estimates, which are stored in second and third data structures, respectively. One or more memory optimizations are used to increase performance. Before storing the second and third data structures in a memory, the second and third data structures are sparsified to only include the outputs in specific regions of interest.
