Abstract
A radar system for tracking airborne targets, in which the transmitted pulse signal is swept over a predetermined frequency range (3). A local oscillator (15) in the receiver is swept over a similar frequency range the L.O. sweep modulation being initiated (20) by the first significant target return signal. Reflectors on the target at different ranges therefore produce different I.F.s in the receiver. Discrimination between the various target reflector features is thus achieved by filtering (25, 27, 29) the I.F. signals in a series of small bands, each band corresponding to a particular target-feature range. Azimuth, elevation and magnitude of a target feature can thus be obtained for each range cell.
