Range sidelobe elimination in maximal sequence phase coded C.W. radars
Abstract
Elimination of the range sidelobe of the autocorrelation of the periodic binary maximal sequence has been achieved. A new property of the m-sequence is defined. As a result the ambiguity function of an m-sequence PSK CW radar coincides with the ambiguity function of the equivalent pulse radar as far as the range and velocity resolution are concerned. The signal to noise deterioration due to the post-correlation implementation of the new property is insignificant.
