| 发明名称 | Method and radar system for repetition jammer and clutter supression | ||
| 摘要 | A method for suppressing repetition jammer signals and/or clutter signals by using a radar system wherein said radar system comprises, at least one wideband arbitrary waveform generator, for creating arbitrary waveforms, and at least one antenna operating with wide instantaneous bandwidth, enabling direction dependent waveform radiation, wherein said method comprises the steps of transmitting different waveforms in different directions; adapting transmitted waveforms in different directions depending on received waveforms such that a normalised signal to noise-jammer ratio, NSNJR, is maximized; and thereby providing received signals from repetition jammers and/or clutter that are substantially orthogonal to a received signal from a target; thereby achieving suppression of the repetition jammers and/or clutter. | ||

| 主权项 | 1. A radar system for suppressing at least one of repetition jammer signals or clutter signals, said radar system comprising: at least one wideband arbitrary waveform generator, for creating arbitrary waveforms; and at least one antenna operating with wide instantaneous bandwidth, enabling direction dependent waveform radiation; wherein said radar system is configured to transmit different waveforms in different directions depending on received waveforms, such that a normalized signal to noise-jammer ratio, NSNJR, is maximized, which provides that received signals from the at least one repetition jammers or clutter are substantially orthogonal to a received signal from a target and thereby achieving suppression of the at least one repetition jammers or clutter. | ||
