Abstract

Abstract An arrangement for generating a firing or triggering signal for a projectile which is conveyed in a flying body overflying a target, wherein a target identifying circuit requires a processing period for the identification of a detected target pursuant to predetermined characteristics, and in which, subsequent to a waiting period dependent upon the flying altitude, there occurs a delay or lag period between the initiation of the firing signal and the ejection or, respectively, target impact of the projectile. For the target determination, an optical sensor arrangement is directed at a first acute angle relative to the flight trajectory of the flying body; wth this angle being so calculated that at a minimum flying altitude of the flying altitude of the flying body, the flying time from the target determination up to the overflight of a certical above the target is at least equal to the sum of the processing period and the delay or lag period, and in which the sensor arrangement is set a second acute angle which is larger than the first angle after the identification of a selected target, and which takes into consideration the delay period and the flying altitude.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 208 words
In an arrangement for the generating of a firing signal for a projectile conveyed in a flying body overflying a target, including a target identifying circuit requiring a processing time period for the identification of a detected target pursuant to predetermined characteristics, and wherein after a waiting time period dependent upon the flying altitude there occurs a lag time between the initiation of the firing signal and the ejection of target impact of the projectile; the improvement comprising: optical sensor means for target detection being arranged at a first acute angle relative to the flight path of the flying body, said angle being measured so that at a minimum flying altitude of the flying body the flying time from target detection to overflight of a vertical from the target is at least equal to the sum of the processing time period and lag time; means for positioning said sensor means upon identification of a selected target at a second acute angle which is larger than the first angle and takes into consideration the lag time, said second angle conforming to the lag time and an altitude-dependent corrective time, and said firing signal being triggered after the corrective time period when said identified target is below said second angle.
Claim 2
Dependent Claim 208 words
In an arrangement for the generating of a firing signal for a projectile conveyed in a flying body overflying a target, including a target identifying circuit requiring a processing time period for the identification of a detected target pursuant to predetermined characteristics, and wherein after a waiting time period dependent upon the flying altitude there occurs a lag time between the initiation of the firing signal and the ejection of target impact of the projectile; the improvement comprising: optical sensor means for target detection being arranged at a first acute angle relative to the flight path of the flying body, said angle being measured so that at a minimum flying altitude of the flying body the flying time from target detection to overflight of a vertical from the target is at least equal to the sum of the processing time period and lag time; means for positioning said sensor means upon identification of a selected target at a second acute angle which is larger than the first angle and takes into consideration the lag time, said second angle conforming to the lag time and an altitude-dependent corrective time, and said firing signal being triggered after the corrective time period when said identified target is below said second angle.
Claim 3
Dependent Claim 48 words
Arrangement as claimed in claim 1, comprising means for having said sensing means track said selected target after identification thereof, and calculating said second angle from the flying altitude and the lag time, and triggering said firing signal when said sensor means is tacked within said second angle.
Claim 4
Dependent Claim 48 words
Arrangement as claimed in claim 1, comprising means for pivoting said sensor means into the current angle determined after identification of a selected target from the flying altitude and the lag time, and wherein said firing signal is triggered when said selected target is below said second angle.
Claim 5
Dependent Claim 44 words
Arrangement as claimed in claim 1, comprising a second sensor means at a fixed second angle in consideration of the lag time, said firing signal being triggered upon passing of a corrective time period during passage over the target by said second sensor means.
