ABSTRACT:
A method is described for detecting an object with target radar. After the first detection of an object, the antenna is tilted. The original direction towards the object is restored by electronically steering the emitted beam. The beamsteering is obtained by changing the frequency of the emitted signal. Thus, the object may be detected several times on different frequencies. The method is particularly applicable in search and track radars.
