Suppression of range sidelobes in bistatic radars
Abstract
A bistatic radar is considered in which linear-FM pulses are employed to obtain the needed range resolution while using a long pulse. Range sidelobes of the pulse received over the direct path from the transmitter tend to interfere with the return from the target. It is shown that conventional weighting schemes give little or no suppression of some of the range sidelobes of a linear-FM rectangular pulse passed through a matched filter. This is explained by the irregular spacing of the sidelobes in the pulse when it passes through the matched filter.
