Abstract
Abstract A multi-channel radar apparatuses optimizes the number of channels used for detecting a body in terms of position detection precision and processing time reduction. The multi-channel apparatus detects the position of the body that produces reflecting waves by calculating, for example, the center of gravity using only the received signals of monostatic channels (B1, B3, and B5) when the level of the received signals is high and using the received signals of the monostatic channels (B1, B3, and B5), as well as the received signals of bistatic channels (B2 and B4) when the level of the received signals is low.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
158 words
A multi-channel radar apparatus comprising a plurality of monostatic channels each of which receives a reflected wave of a beam transmitted from a source channel as a received signal of that said source channel, and at least one bistatic channel each of which receives a reflected wave of a beam transmitted from one channel as a received signal of an adjacent source channel, wherein: the apparatus includes means for detecting a position of an object by using only the received signals of said monostatic channels when a level of the received signals is high and by using both the received signals of said monostatic channels and the received signals of said bistatic channels when the level of the received signals is low, the level of said received signals being high when it exceeds a predetermined threshold value, and the level of said received signals being low when it is equal to or less than said predetermined threshold value.
Claim 2
Dependent Claim
158 words
A multi-channel radar apparatus comprising a plurality of monostatic channels each of which receives a reflected wave of a beam transmitted from a source channel as a received signal of that said source channel, and at least one bistatic channel each of which receives a reflected wave of a beam transmitted from one channel as a received signal of an adjacent source channel, wherein: the apparatus includes means for detecting a position of an object by using only the received signals of said monostatic channels when a level of the received signals is high and by using both the received signals of said monostatic channels and the received signals of said bistatic channels when the level of the received signals is low, the level of said received signals being high when it exceeds a predetermined threshold value, and the level of said received signals being low when it is equal to or less than said predetermined threshold value.
Claim 3
Dependent Claim
41 words
A multi-channel radar apparatus according to claim 1 , wherein the level of said received signals is high when one or more among the received signals of all channels comprising the monostatic channels and bistatic channels exceeds said predetermined threshold value.
Claim 4
Dependent Claim
41 words
A multi-channel radar apparatus according to claim 1 , wherein the level of said received signals is high when two or more among the received signals of all channels comprising the monostatic channels and bistatic channels exceeds said predetermined threshold value.
Claim 5
Dependent Claim
40 words
A multi-channel radar apparatus according to claim 1 , wherein the level of said received signals is high when a summation of the received signals of all channels comprising the monostatic channels and bistatic channels exceeds said predetermined threshold value.
Claim 6
Dependent Claim
52 words
A multi-channel radar apparatus according to claim 1 , wherein the apparatus calculates a direction of the object that generates the reflected waves as a value obtained by averaging a direction of each of said channels which have been weighted by the level of the received signals of each of said channels.
Claim 7
Dependent Claim
21 words
A multi-channel radar apparatus according to claim 1 , wherein the apparatus provides a transceiving antenna for each of said channels.

Claim 12
Dependent Claim
30 words
A multi-channel radar apparatus comprising a plurality of channels, and means for reducing a number of said channels used for detecting an object as a level of received signals increases.
Claim 13
Dependent Claim
49 words
