Title: Target detecting equipment of radar
Inventor: SAKAI MASAYOSHI
IPC: G01S7/292
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the accuracy in detection of a target, such as frequent occurrence of a false target and lowering of a rate of target detection, which takes place in a transitional state till a control threshold value just after a switchover of a state of radar operation reaches a fresh expected value, by correcting the amplitude of the maximum value of a reception signal corresponding to a cell so that the expected value of the control threshold after the switchover may not vary from that before the switchover, on the occasion when the state of radar operation is switched over. SOLUTION: According to a state of radar operation, a radar reception signal is subjected to amplitude conversion so that an expected value of the maximum value of the reception signal for each cell as basic data for determining a control threshold THC be always a prescribed value, and thereby the expected value of the control threshold THC is always made the prescribed value. By this method, transitional fluctuation of a detecting threshold for target detection determined on the basis of this control threshold, which accompanies a change in the state of radar operation, is eliminated and frequent occurrence of false targets and deterioration of a rate of target detection at the time of a switchover of the state of radar operation are eliminated. Thus, stable target detection can be continued.

Abstract: PURPOSE:To generate the miscellaneous motions of an object by changing input data quantitatively by generating the motion of a mobile body based on a value that quantity given to a point to be observed is observed by the moving body. CONSTITUTION:One or more quantities other than a number to distinguish the kind or the individual of the body are given respectively to one or more points (point to be observed) 2b of space where the moving body 1b is included, and the motion of the mobile body 1b is generated based on the value that one, at least, of the quantities given to the point is observed by the mobile body 1b. Since the basis of the generation of the motion is the quantity, and is not the one for distinguishing the kind or the individual of the body, it is not necessitated to describe a program corresponding at every kind of the body in a circumference, and besides, because a method to generate the fundamental part or the all of the motion from the value of the quantity observed by the moving body 1b is generalized, it is not necessary to describe the program at every kind of the mobile body 1b respectively. Besides, the expression of the motion corresponding to the difference of the individual among the mobile bodies of the same kind or the body having intermediate substance between the different kinds can be easily performed by the operation of the quantity.
