1. A method comprising:
steering, via a frequency scanning antenna (FSA), a radar beam over an angular range;
detecting a return signal; and
generating a first windowed return signal by applying a first angular window function to the return signal, wherein the first angular window function corresponds to a first angular sector of the angular range; and
generating a second windowed return signal by applying a second angular window function to the return signal, wherein the second angular window function corresponds to a second angular sector of the angular range that overlaps with the first angular sector, wherein the method comprises:
generating windowed return signals by applying angular window functions to the return signal, wherein the angular window functions correspond to a quantity of angular sectors of the angular range, wherein the windowed return signals comprises the first windowed return signal and the second windowed return signal and the angular window functions comprise the first angular window function and the second angular window function, wherein the quantity of the angular sectors of the angular range is (1) greater than two times an angular coverage range of the FSA divided by a half power beam width of the FSA or (2) is equal to the angular coverage range of the FSA divided by the half power beam width of the FSA.
