Abstract
Abstract A firing circuit for a projectile 10 includes a proximity fuze 11 which can be set to different target distances H1, H2. For the purpose of optimally combating different types of targets 13, 14, 15, a target sensor 17 is associated with the proximity fuze 11 so as to detect characteristic target properties and take care that proximity fuze 11 responds either at a height H1 or at a lower height H2, and causes an explosive charge 10a to detonate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
73 words
A method of actuating a proximity fuze in a projectile which is fired at a target in a target area, said proximity fuze being adjustable for different target distances, comprising: providing a target sensor in the projectile to detect characteristic properties of targets disposed in the target area; and controlling the proximity fuze to respond at different heights above the earth's surface depending upon the type of target detected by the target sensor.
Claim 2
Independent Claim
73 words
A method of actuating a proximity fuze in a projectile which is fired at a target in a target area, said proximity fuze being adjustable for different target distances, comprising: providing a target sensor in the projectile to detect characteristic properties of targets disposed in the target area; and controlling the proximity fuze to respond at different heights above the earth's surface depending upon the type of target detected by the target sensor.
Claim 3
Independent Claim
75 words
A device for actuating a proximity fuze in a projectile which is fired at a target in a target area, said proximity fuze being adjustable for different target distances, comprising: a target sensor provided in the projectile to detect characteristic properties of targets disposed in the target area; and means for setting the proximity fuze to respond at different heights above the earth's surface depending upon the type of target detected by the target sensor.
Claim 4
Independent Claim
75 words
A device for actuating a proximity fuze in a projectile which is fired at a target in a target area, said proximity fuze being adjustable for different target distances, comprising: a target sensor provided in the projectile to detect characteristic properties of targets disposed in the target area; and means for setting the proximity fuze to respond at different heights above the earth's surface depending upon the type of target detected by the target sensor.
Claim 5
Dependent Claim
14 words
A device according to claim 2, wherein the target sensor comprises a metal detector.
Claim 6
Dependent Claim
40 words
A device according to claim 3, wherein the target sensor and proximity fuze are structurally combined and include a radar transmitter/receiver with which the height of the projectile above the ground as well as characteristic target properties can be detected.
Claim 7
Dependent Claim
40 words
A device according to claim 2, wherein the target sensor and proximity fuze are structurally combined and include a radar transmitter/receiver with which the height of the projectile above the ground as well as characteristic target properties can be detected.
Claim 8
Dependent Claim
14 words
A device according to claim 2, wherein the target sensor comprises a radar transmitter/receiver.
Claim 9
Dependent Claim
18 words
A device according to claim 2, wherein the target sensor comprises a metal detector and a radar transmitter/receiver.
