Classification: CPC G | IPC G

Claim 0:
1. A Signal Processing Unit (SPU), comprising:
a radar memory configured to store a radar data cube;
a thresholding circuit connected to the radar memory, and configured to detect a peak cell of the radar data cube, and to output an identification of the peak cell and energy values of the peak cell and its adjacent cells;
an interpolation circuit coupled to the thresholding circuit, and configured to determine and transmit from the SPU to a Digital Signal Processor (DSP), a relative position of the peak cell between the adjacent cells based on the energy values output from the thresholding circuit; and
a memory buffer connected between the thresholding circuit and the interpolation circuit buffer, and configured to store the identification of the peak cell and energy values of the peak cell and its adjacent cells output by the thresholding circuit,
wherein the interpolation circuit is configured to determine the relative position of the peak cell between the adjacent cells based on energy values obtained from the memory buffer.
