Abstract : The patent describes a coherent, 13 bit phase reversal pulse modulator and pulse compression filter for increasing the range resolution of a coherent radar. The transmitted pulse is subdivided into equal duration bits, and as the pulse is being formed each bit may or may not be shifted in phase determined by a digital code generator. The range resolution of which this pulse reversal modulated pulse is capable is achieved by processing the radar return signal in an approximation to a matched filter.
