Sound measurement technology (military)

from Wikipedia, the free encyclopedia

The sound ranging is a since the First World War developed method for localization of artillery pieces by measuring the transit time differences of the sound between multiple microphone -Messstellen.

The measuring system is built on a measuring base width of about 10 km, whereby the sound events picked up by precise microphones are transmitted to a central evaluation, where they are recorded with a storage oscilloscope , which is similar to an EKG device.

The measurement of the time differences leads to the localization of the sound event. The range of the sound measurement is (depending on the weather) up to 20 km. The sound measurement method is an essential means of reconnaissance for "general fire fighting", ie fighting the opposing artillery in combat .

This localization method (incorrectly called localization method ) represents a "passive" reconnaissance means, which has the advantage over the mostly used "active" reconnaissance of being "non-emissive" and thus not remotely detectable by the enemy, as there is no own signal , as with the active one Radar system that is broadcast. The arrival times and in particular their difference to one another, combined with the exact measurement of one's own location, allow both the exact distance measurement ( echolocation ) and the detection of the direction and, derived from this, the original location of the target variable from the measured variables of the speed of sound at the measured temperature and air pressure at the time of measurement .

Using this system a. the Bundeswehr and the Dutch army in a modernized form.

A sound measurement train integrated in a reconnaissance battery is used. This consists of two sound measurement advance warning groups, each with two Mercedes (Wolf) off-road vehicles.

These advance warning teams trigger six microphones behind, which are set up a few kilometers away (6 measuring cabins Daimler-Benz Unimog 404 , later Unimog 435 ). The signals captured in this way are sent by radio to an evaluation booth (Mercedes-Benz NG or MAN 630 ) and evaluated there.

The system can pinpoint the position of a bang (gun, etc.) to within one meter.
