Abstract
A radar for locating and tracking objects based on the use of a pulsed waveform, each pulse of the pulsed waveform being made up of a plurality of spectral components having different frequencies, including an antenna. The radar further includes a transmitter operatively coupled to the antenna for generating the plurality of spectral components that make up each pulse of the pulsed waveform and a receiver operatively coupled to the antenna for receiving signals at the frequencies of the plurality of spectral components. The radar also includes a signal processor operatively coupled to the receiver for processing the received signals in order to generate and output a radar presentation and to detect the presence of other signals at particular frequencies, a display operatively coupled to the signal processor for displaying the radar presentation, and finally a controller operatively coupled to the transmitter and the signal processor for varying the frequencies at which the plurality of spectral components are generated, such that the transmitter generates spectral components at frequencies different from the frequencies of other signals detected by the signal processor.
