Abstract: A Signal Processing Unit (SPU) having a thresholding circuit configured to detect a peak cell of a radar data cube, and to output an identification of the peak cell and energy values of the peak cell and its adjacent cells; and 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.

Abstract: A method for processing radar signals includes emitting a first radar signal via a transmitting antenna of a first radar unit, where the first radar signal is phase modulated using a first code and a first frequency offset is added to at least a portion of the first radar signal, and emitting a second radar signal via a transmitting antenna of a second radar unit, where the second radar signal is phase modulated using a second code. The first code and the second code are orthogonal to each other and the first radar unit and the second radar unit are loosely coupled with each other. The method further includes receiving a combined radar signal via a receiving antenna of the first radar unit, where the combined radar signal comprises a reflections of the first and the second radar signals, and processing the combined radar signal at the first radar unit.
