Abstract
Abstract A detection system detects objects in the path of a vehicle on which it is mounted by transmitting a beam of radiation broad in comparison with the beam width of the receiving antenna (7A, 7B, 7C, 9, 11) and detecting radiation reflected back from the objects to the receiving antenna. The receiving antenna comprises a plurality of discrete antenna elements (7A, 7B, 7C), each of which receives radiation from a given range of directions of the obstacle relative to the vehicle. <IMAGE>

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
A detection system suitable for use on a road vehicle for collision avoidance purposes comprising means (1, 3) for transmitting a beam of radiation and a receiving antenna (7A, 7B, 7C, 9) for detecting radiation reflected back from objects in the path of said beam; characterised in that said transmitted beam is relatively broad compared with the beam width of the receiving antenna (7A, 7B, 7C, 9, 11) and the receiving antenna (7A, 7B, 7C, 9, 11) is arranged so that its direction of look can be varied.
Claim 2
Dependent Claim
65 words
A system as claimed in Claim 1 in which said receiving antenna (7A, 7B, 7C, 9, 11) includes a plurality of discrete antenna (7A, 7B, 7C) elements and lens means (9) arranged to focus radiation reflected from objects in different directions onto different ones of said antenna elements (7A, 7B, 7C) and switching means for switching from one antenna element (7A, 7B, 7C) to another.
Claim 3
Dependent Claim
25 words
A system as claimed in Claim 2 in which said receiving antenna (7A, 7B, 7C, 9, 11) includes three discrete antenna elements (7A, 7B, 7C).
Claim 4
Dependent Claim
20 words
A system as claimed in Claim 2 or 3 wherein said discrete antenna elements (7A, 7B, 7C) are patch antennas.
Claim 5
Independent Claim
24 words
A system as claimed in Claims 2, 3 or 4 wherein said antenna elements (7A, 7B, 7C) are positioned in a horizontally spaced relationship.
Claim 6
Dependent Claim
18 words
A system as claimed in Claim 1 in which the receiving antenna comprises a multi-element phased array antenna.
Claim 7
Dependent Claim
18 words
A system as claimed in Claim 1 in which the receiving antenna comprises a frequency scan array antenna.
