  • Multimode radar for road vehicle blind-zone target discrimination
    Patent number: 5325097
    Abstract: A road vehicle radar system for discriminating between hazard and non-hazard targets within a predetermined zone uses a pair of frequency modulated continuous wave radar cycles (FM-CW) and a single continuous wave cycle (CW) in the generation of radar quantities for measuring target range and apparent target velocity. Measured quantities from the FM-CW and CW cycles are compared with predetermined quantities for discriminating between hazard and non-hazard targets.
