MDI AS-113/12U

Miss distance indicator MDI

MDI model for UAVs

The universal 12-sector Miss Distance Indicator MDI AS-113/12U is intended to be installed in UAVs  (Unmanned Aerial Vehicles). The MDI is a universal type, i.e. it handles all target courses relative the firing gun or missile, i.e. all types of attacking and passing target courses. The 12-sector MDI AS-113/12U detects acoustically the shock wave generated by the passing supersonic projectile. The miss distance is determined by the amplitude of the shock wave while the angular position (sector) is determined from the hit order between the indicator´s different pressure sensors.

The miss distance and sector of the projectiles are measured in real time and transmitted as raw data via the special designed VHF/UHF transmitter to the scoring station. Since raw data is used, all calculations are made in the scoring station. A recalculation of the scoring result, with later more accurate parameters, can easily be made in the scoring station for further improved accuracy.

The MDI consists of two Small Microphone Clusters SMC-3/left and right (to be installed at the wing tips), a Target Unit Processor TUP-23 (to be installed in the target body), cables and an antenna.  Several antenna types areavailable to fit the most common UAVs on the market. The MDI is powered from a rechargeable battery which is housed in the TUP-23. The TUP-23 unit is waterproof. Air Target´s products can very easily be modified to meet our customer´s requirements.
