FR2640039A1 - LAUNCHING SYSTEM FOR GUIDED WEAPONS - Google Patents

Abstract

The launch facility 5 is fitted with a warning device which, in the event of the appearance of disturbing infrared ray emitters in the field of vision of the OA tracking facility, prompts the service personnel or the operator. launch facility 5 itself to take steps to avoid a false launch.

Description

The invention relates to a launching installation for guided weapons

  comprising a warning device which is connected to light and / or thermal radiation detectors. An installation of this type is known from patent application DE-34 02 167. This document aims, in the event of the appearance of several physical states detectable with detectors, to identify whether it is a nuclear attack, in order to trigger a counterattack. However, this document does not indicate how the guided weapon launched during the counterattack must be aimed at a target or how the

  command must work in the event of the appearance of false targets.

  The object of the invention is to subsequently equip a launching installation for guided weapons so that, in the event of the appearance of disturbing infrared radiation in the region of an optical axis of the installation oriented on a target, a warning can be issued at least before the planned shot and

  other measures are triggered. -

  This object is achieved in the case of a launching installation for guided weapons by the fact that: a) an infrared tracking installation is oriented on a target and emits output signals proportional to the intensity and / or the direction of one or more infrared emitters located in the target area; b) the output signal corresponding to the intensity is compared with an adjustable signal threshold; c) if the signal threshold is exceeded, a warning signal is produced which is indicated to the service personnel and / or automatically causes a countermeasure in the launching installation in order to avoid a false

launch.

  According to advantageous nonlimiting embodiments of the invention: 1) the infrared tracking installation can be constituted by the series mounting of an infrared filter, of an infrared with respect to the main axis of the sensor infrared, and another output signal A corresponding to the intensity of the

regu infrared radiation.

  This output signal A is brought to an adjustable threshold value switch 6. The threshold with which the output signal A is evaluated can be set as a fixed value or adjusted adaptively on the basis of another control signal not described in detail. The output signal W which is emitted when the command signal threshold is exceeded, as a signal

  warning W, different warning devices.

  In the simplest case, the warning signal W activates an optical and / or acoustic alarm 7a, b which indicates to the service personnel the appearance of a transmitter disturbing infrared rays in the field of vision of the installation. of

QA marking.

  Another display possibility provides for a monitor 10 which is connected to the launching installation 5. In the case where the warning signal W appears, this can be indicated to the service personnel for example on the screen 9. In In connection with the direction signals X, Y of the locating system, there are a multitude of other display possibilities. By way of example, there will be direction arrows 8 which light up, or a particular display mode on the screen 9. It is also possible to provide for manual or automatic switching to another field

of vision.

  In all cases, the warning displays must prompt the service personnel to take action themselves, for example the interruption of the planned launching of a guided weapon or the transfer to a target which can be observed without disturbance, in particular occurrence of a disturbing infrared ray transmitter preventing the successful launch of a guided weapon. Similarly, it is possible, using the direction signals X, Y and the warning signal W, to trigger one of the measures listed automatically in the launching installation 5 and thus avoid

a false launch.
