Claim 12:
13. A method for a Signal Processing Unit (SPU) processing a radar data cube, comprising:
detecting, by a thresholding circuit connected to a radar memory configured to store the radar data cube, a peak cell of the radar data cube;
outputting, by the thresholding circuit, an identification of the peak cell and energy values of the peak cell and its adjacent cells;
determining and transmitting from the SPU to a Digital Signal Processor (DSP), by an interpolation circuit coupled to the thresholding circuit, a relative position of the peak cell between the adjacent cells based on the energy values output from the thresholding circuit; and
storing, in a memory buffer connected between the thresholding circuit and the interpolation circuit, the identification of the peak cell and energy values of the peak cell and its adjacent cells output by the thresholding circuit,
wherein the determining the relative position of the peak cell between the adjacent cells is based on energy values obtained by the interpolation circuit from the memory buffer.
