A radar system comprising a dielectric lens (1) for receiving HF arranged so as to focus the radiation received through a substrate (2) on a network of integrated antenna/mixer circuits supported on the rear face of the substrate and an HF generator which applies radiation through a dielectric matching device to the rear face of the substrate so that some of the radiation is applied to the antenna/mixer circuits in order to form the local oscillator signal intended for the circuits while the rest passes through the lens to form the radar output signal. Such a radar system may be fixed on board a guided missile so that it has a field of view which is fixed in relation to the missile, this field of view being moved or subject to scanning by movement of the missile en bloc, for example by rotation of the missile. <IMAGE>
