Radar system and method for detecting targets in clutter using target intensity and angular position

摘要

A radar system (20) includes a radar receiver (22) that provides the amplitude and the angular position of a plurality of return signals. A computer (30) forms a test function of amplitudes and angular positions of the plurality of return signals and compares the test function with a threshold value. Returns associated with a test function whose value is equal to or greater than the threshold value are determined to be targets (26), and those with lesser values are considered clutter (28).
