Definitions

  • the subject of the invention is a method of terrain reconnaissance by means of a mortar bomb.
  • Methods of terrain reconnaissance are known for example from patent specification US 3,962,537 . These methods consist in that a mortar bomb, equipped with an observation unit with a camera, a parachute, and a transmitter, is fired toward a terrain subject to a reconnaissance.
  • the observation unit is disconnected from the shell of the mortar bomb in order to monitor the terrain by means of the camera falling down slowly with the parachute, simultaneously transmitting images of the terrain by means of radio, infrared or other radiation, to a receiver installed at a command post, where the received signals are suitably processed, registered or displayed directly on a display unit of a computer.
  • the observation unit does not fall down steadily.
  • the airborne imaging system of the present invention includes a blister housing attached to a host vehicle.
  • a sensor suite is deployed from the blister housing.
  • the sensor suite is eccentrically weighted to induce a pendular motion as it is suspended from a paradevice.
  • the paradevice is designed for angular motion and the look down angle of the imaging system can be adjusted from the vertical.
  • the data is broadcast to a receiving station that processes individual frames to create a continuously updated mosaic of the area of interest.
  • the object of the invention is to create a method eliminating the rotation of the image displayed on the display unit.
  • the essence of the method consisting in firing a mortar bomb, equipped with an observation unit comprised of a camera, a parachute, and a transmitter, toward a terrain subject to a reconnaissance, where after a specified time the observation unit is separated from the shell of the mortar bomb and monitors the terrain, simultaneously sending a signal from the camera by means of radio, infrared or other radiation to a receiver situated at a command post where signals received from the camera are displayed on a computer display unit after being converted into the digital format, lies in that a deviation value of a determined axis of the observation unit from the north-south direction N-S is detected in the observation unit for a single image by means of a magnetometer or a satellite navigation system GPS, said consecutive deviation values being converted into a N-S deviation signal sent synchronically with the signal from the camera to the receiver, in which the position of each consecutive image on the display unit is corrected by its corresponding value of the deviation from the N-S direction by means of a known image rotation algorithm.
  • a shell of a mortar bomb comprises an observation unit provided with a TV camera K, a parachute, a radio transmitter N, a magnetometer M, a disrupting charge L together with its fuse, a supply unit Zn for an observation unit with an inertial power-on switch Wb, with a time-lag cut-out switch Wc for switching off a supply unit Zn, as well as with a controller Sn.
  • the mortar bomb is fired by means of a mortar. Before dropping the mortar bomb into a tube, a delay time is set for the disrupting charge L in the observation unit.
  • the observation unit in the fired mortar bomb is fed with a supply voltage by means of the inertial power-on switch Wb, and after the determined delay time the disrupting charge L is initiated, the parachute is opened, and the observation unit slowly falls down.
  • the camera K generates a video signal corresponding to the observed terrain being in its view.
  • the values of a momentary deviation of the observation unit from the north direction are detected, and information concerning these deviation values is encoded in a sound channel of a TV signal, said signal being transmitted by the radio transmitter N to a command post.

Verfahren für Geländeaufklärung mithilfe einer Mörserbombe, bestehend daraus, dass die Mörserbombe mit einer Beobachtungseinheit, die eine Kamera (K), einen Fallschirm und einen Sender (N) aufweist, in Richtung eines aufzuklärenden Geländes abgeschossen wird, wobei die Beobachtungseinheit nach einer spezifizierten Zeit von der Hülle der Mörserbombe getrennt wird und das Gelände überwacht und gleichzeitig von der Kamera (K) über Funk, Infrarot- oder andere Strahlung ein Signal an einen Empfänger (0) sendet, der sich an einem Befehlsstand befindet, wo die von der Kamera (K) empfangenen Signale nach Umsetzung in das digitale Format auf einem Computer-Bildschirmgerät (E) angezeigt werden, dadurch gekennzeichnet, dass ein Abweichungswert von einer spezifizierten Achse der Beobachtungseinheit von der Nord-Süd-Richtung N-S in der Beobachtungseinheit für ein einzelnes Bild mithilfe eines Magnetometers (M) oder eines Satelliten-Navigationssystems GPS erkannt werden, wobei die konsekutiven Abweichungswerte in ein N-S-Abweichungssignal umgewandelt werden, das synchron mit dem Signal von der Kamera (K) an den Empfänger (0) gesendet wird, in dem die Position jedes konsekutiven Bilds auf der Bildschirmeinheit (E) durch ihren entsprechenden Wert der Abweichung von der N-S-Richtung mithilfe eines bekannten Bildrotationsalgorithmus korrigiert werden.
