| description | A multi-mode radar system, radar signal processing methods and configuration methods, including using predetermined, range/mode-specific pushing windows to perform windowing on range and velocity object data before performing an FFT on the windowed object data matrix to generate a three-dimensional object matrix including range, velocity and angle data. The individual windows have an angular spectral response that corresponds to a combined angular coverage field of view of the transmit and receive antennas for the corresponding mode to minimize the total weighted energy outside the main lobe and to provide increasing spectral leakage outside the combined angular coverage field of view with angular offset from the main lobe to push out much of the spectral leakage into regions where leakage tolerance is high due to the corresponding combined angular coverage field of view of the transmit and receive antennas. |
