ABSTRACT:
A coherent pulse radar system capable of eliminating a signal associated with a multiple time around path or capable of removing range ambiguity of this multiple time around signal. The radar system includes a device for changing phases of transmitted pulses, for phase detecting received radar pulses with respect to transmitted pulses associated with the present and preceding reception period, and for integrating phase detected signals in a coherent manner.
