초록

A single transmit multi-receiver modulation radar modulates radar return signals received through an associated receive-signal path with one of a plurality of differing modulation waveforms having low-cross correlation products. Each receive-signal path may be associated with a different receive direction. The differently modulated return signals from each receive-signal path may be combined and correlations may be performed on the combined and differently modulated radar return signals using the modulation waveforms to locate a target. In some embodimen...

청구항

What is claimed is: 1. A receiver comprising: a plurality of modulators, each modulator to modulate signals received through an associated receive-signal path with one of a plurality of differing modulation waveforms having a low-cross correlation product; combining circuitry to combine the modulated signals from each receive-signal path; and signal processing circuitry to perform correlations on the modulated combined signals using the modulation waveforms. 2. The receiver of claim 1 wherein the modulation waveforms comprise a plurality of substanti...
