Abstract: The present invention relates to a radar system haing a high range resolution. Said radar system emits series of n pulses whose carrier frequencies are distributed within a band B and whose time positions are associated with the frequency in accordance with a linear reelationship. The echoes received in return are demodulated with the corresponding waves which gave rise to them, and supplied to a filter bank which produces at different outputs, different signals which correspond to separate objects or parts of objects.

Abstract: A multifrequency measurement pulse radar system transmits at least two series of pulses of a same repetition frequency but of different carrier frequencies. The reflected signals are demodulated by a single reference signal and filtered in at least one Doppler filter bank. Each object of the space is characterized by at least two signals, which are picked off separately at the corresponding outputs of the Doppler filters. These signals are compared in pairs in a phase comparator which delivers the range data.
