Abstract:
A method of radar signal processing to detect a target object, the method comprising the steps of:transmitting radar signals from a radar system, the radar signals being transmitted according to a predetermined frequency scheme; receiving signals at the radar system within a frequency band, the frequency band including frequencies of the predetermined frequency scheme and also including frequencies of return signals comprising portions of the radar signal echoed from the target object; coherently integrating the received signals to transform time domain data of the received signals into frequency domain templates of data; arranging the frequency domain templates into an array matrix; processing at least a portion of the frequency domain templates to form presums; storing the presums required for use in forming higher level presums or acceleration bins; forming acceleration bins from the presums; and analyzing the acceleration bins to detect the presence of a return signal from the target object.
