Abstract A 2-D pulse doppler radar for air-route surveillance is described, which is provided with a particular arrangement and combination of two antenna feeders, a microwave changeover switch for said feeders, a control device for said changeover switch controlled by a radar computer program adaptive with respect to the environment and connected to the TWS (track while scan) tracker device. This radar will improve the performance of known 2-D radar equipment, in that: - it makes possible to radiate, according to a pre- established program, only in the minimum indispensable space regions, so reducing the risks for the radar to be detected/identified and/or to be counteracted by ARM (anti- radiation missile) weapons; - it supplies under form of digital data and symbolic information on the radar PPI (plan position indicator) in addition to range and deflection, also rough elevation data on tracked targets without having to resort to expensive or complicated equipment and without appreciable impairment of the other normal features of 2-D radars in terms of surveillance capability and TWS (track while scan) precision, other conditions being equal.
