Air Target Sweden

Calculating projectile miss distance

The shock wave generated by a passing supersonic projectile or missile is detected by an array of pressure sensitive sensors installed on or close to the target.

The amplitude and the time differences between the different sensors are used to calculate the shortest distance between the target and the projectile (the miss distance), and in what angular position the projectile passed. The scoring data are presented in real time on a colour graphic computer display. Data transmission between sensors and display is via a radio link.

Gunnery training with acoustical scoring

Scoring gives the gunner and the weapon system operator real time information in the virtual “scoring board”. This information gives a picture of each round “hitting” the “scoring board”. The angular position of the score as well as a score too far off can immediately guide the gunner to improve his direction of fire. The improved results can be verified as they appear on the “scoring board”.

Firing situations

Acoustical scoring is useful for calibers from 5.56 to 5″ and above and missiles (rounds need to be supersonic in the target area). Acoustical scoring can be used for all firing situations i.e. AIR to AIR, AIR to GROUND, GROUND to AIR, GROUND to GROUND, and the corresponding naval applications.

LOMAH system

The “LOMAH” system is our latest developed system and has been delivered in large numbers to many customers since 2006. LOMAH is a calibration free acoustic scoring system suitable for scoring of all supersonic caliber sizes.

Typical areas of application:

• Firing range and combat soldier training SASS-4/9
• Tank Target Scoring System TTSS-4/9
• All type of static and moving targets, including pop-up targets
• Aircraft firing against ground targets ATG

The use of a scoring system will increase the throughput and make the validation of the gunners efficient and very cost effective.

The firing result is presented on a Visual Display Unit (VDU-1) placed close to the gunner. Several target figures are available, such as half and full size soldier figures, or a ten ring standard target.

Up to 10 ea. lanes each containing several SASS units can be connected to a Range Office Presentation Unit (ROPU) for presentation of the firing result. The result can be printed as well.

Scoring stations

Mini Marque and Marque scoring stations are used for the collection, calculation, and presentation of real time firing results from up to six targets simultaneously.

The new scoring stations Marque and Mini Marque can receive scoring data from up to six targets (MDIs) simultaneously. The software is based on Windows NT including a SQL data base. Features include: Up to 40 m scoring range; Up to 6,k000 rounds/minute.

Miss distance indicators (MDIs)

Zone, 4- and 12-sector models as well as vector models are available for all type of targets and UAVs.

The universal 12 sector MDI gives the possibility to fire at a target (MDI) coming from any direction. The target towing operator/UAV operator can offer any target courses during the same mission.

Uplink command unit

This is used to remotely change the MDI frequency and sensitivity.

Other equipment includes test equipment to test the complete scoring system, sleeve targets, which are soft targets for various applications (radar, laser), and inboard target towing winches.

Customisation of acoustical scoring systems

Customisation of our products to the customer’s requirements is one of our specialities.
