Abstract
Abstract A collision avoidance and warning system for land vehicles including radar transmission and receiving apparatus (12) for sensing the presence of objects within a spatial range relative to a vehicle, multiple target tracking apparatus (14) receiving an output from the radar transmission and receiving apparatus for tracking a plurality of targets sensed by the radar transmission and receiving apparatus, auxiliary non-radar target sensing apparatus (18) and alarm decision apparatus (16) receiving an input from the multiple target tracking apparatus (14) and from the auxiliary non-radar target sensing apparatus (18) for indicating the alarm status of a target and providing an output indication to alarm generating apparatus (20).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A collision avoidance and warning system for land vehicles comprising: a radar transmitter/receiver for sensing the presence of objects within a spatial range relative to a vehicle; a multiple target tracker receiving an output from said radar transmitter/receiver for tracking a plurality of targets sensed thereby; an auxiliary non-radar target sensor; and an alarm activator receiving an input from said multiple target tracker and from said auxiliary non-radar target sensor for indicating the alarm status of a target and for providing an output indication to alarm generating apparatus.
Claim 2
Dependent Claim
20 words
A system according to claim 1 and wherein said auxiliary non-radar target sensor comprises a laser energy transmitter and receiver.
Claim 3
Independent Claim
27 words
A system according to either of claims 1 and 2 and also comprising an alarm generator for providing an indication of alarm status to a vehicle driver.
Claim 4
Independent Claim
19 words
A system according to any of the preceding claims and wherein said radar transmitter/receiver comprises plural radar antenna means.
Claim 5
Dependent Claim
22 words
A system according to claim 4 and wherein said plural antenna means includes at least one antenna for sensing vehicle ground speed.
Claim 6
Dependent Claim
24 words
A system according to either claim 4 or claim 5 and wherein said plural antenna means includes a plurality of antennas for target detection.
Claim 7
Dependent Claim
27 words
A system according to claim 6 and wherein said plurality of antennas are arranged such that their detection regions are distributed in partially overlapping orientation in azimuth.
Claim 8
Dependent Claim
48 words
A system according to claim 7 and wherein said radar transmitter/receiver also comprise an antenna output inspector for comparing the outputs of more than one of said plurality of antennas relating to a given object in order to define the angular position of said object with enhanced resolution.
Claim 9
Independent Claim
35 words
A system according to any of the preceding claims and wherein at least one of said radar transmitter/receiver and said multiple target tracker includes a target motion detector for distinguishing moving targets from stationary targets.
