PIMAWS (Passive IR Missile Approach Warning System) is an Advanced Technology Demonstrator (ATD) for a Passive IR Missile Approach Warning System for use on all flying platforms. The ATD is under development under a contract to the German MoD. First the presentation about PIMAWS will cover the basic design principles to understand, how the system is working (based on real-time signal- and image-processing algorithms): Requirements for passive missile warning. Solution between high repetition rate and sensitivity. PIMAWS design-principles. Status of the Advanced Technology Demonstrator. Image processing algorithms. False alarm reduction. Results of ground based and airborne trials. Video scenes from life firings against the sensor. Integration into Defensive Aids Systems. System Performance. The second part will show, how PIMAWS can be used as a collision avoidance sensor aboard a flying platform: Extended SW function for collision avoidance. Algorithm. Video scenes. The third part will cover the use as a pointable IR staring camera, as an airborne surveillance sensor for SAR and CSAR applications. Video scenes. The end will show different possibilities of the integration into flying platforms.
In the time frame from 1997 to 2001 two R&D studies were carried out by the German MoD under the responsibility from the BWB KG IV 3 and FE III 2 within the area of land mine detection: One ground based vehicle with several different sensors and an airborne version with electro-optical sensors only. In both contracts, Bodenseewerk GmbH was responsible for the real-time image-processing and signal-processing of the electro-optical sensors. In the ground-based version, BGT was subcontracted by Rheinmetall Land Systems. In the airborne version, BGT and Dornier conducted the study on a 50/50 share, but for legal reasons BGT was subcontracted by Dornier. The paper covers three topics: Basics on electro-optical land mine detection, Usable types of sensors. Primary and secondary features. Real-time signal processing. Systolic Array Processor. HW and SW architecture of experimental detection devices. Description of ground-based system, focus on electro-optical system. Images of system and scenarios. Trial results. Description of airborne system. Images of system and scenarios. Trial results.
