In this paper we present a mathematical model, its numerical simulations as well as preliminary experimental results
used for the estimation of the true radiance value as well as the sub pixel position of a point targets that caused to
saturation in the specific pixel at the detector where they appeared. The estimation is done by applying the model for the point spread function of the optics and by using the values of the neighbor and the non saturated pixels.
An evolving combat arena poses an ever-growing hostile fire threat for various ground and airborne targets. Protecting both static posts and moving military platforms against these threats require high performance and affordable solutions, favoring uncooled sensing alert technologies. By analyzing accumulated target and clutter data using new algorithmic and hardware building blocks we establish improved hostile fire indication system configurations. The paper will review new system demonstrations harnessing uncooled IR sensors technology alongside empirical field testing results.
SAPIR system provides a suite of IR based situation awareness functions offered as add on system for ELISRA PAWS
family of missile warning solutions. A major operational need for airborne platforms flying in formation is automatic
collision alert capability. By using covert IR-MWS technology SAPIR passively tracks and monitors wingman position
thereby enabling aircrew to focus on mission goals without compromising their safety. The paper presents results of
operational problem study, system design and field testing demonstration of performance for SAPIR collision alert
function targeting helicopter fleets.
IR MWS systems enjoy full command of the protected own ship surrounding scenery by virtue of its wide field of view staring IR sensors. This paper will explore the operational benefits and technological challenges that are set by ELISRA PAWS wide FOV system infrastructure. Demonstrations will be given for variety of panoramic vision applications that are operated simultaneously with the missile detection system and are used to enhance situation awareness and support platform piloting missions.
Infrared staring sensors used in a large field of view (panoramic) applications such as IRST and MWS are still in need for specialized figures of merit to bridge the gap between feasible laboratory measurements and specification and actual performance. Imaging applications has so far dominated the industry attention and so the need to examine the applicability of conventional analyzing concepts and testing procedures for the new applications was overlooked. In this paper we present a universal test station for panoramic MWS/IRST sensors, designed by Elisra and built by CI-Systems Inc. Following the description of the test station configuration, a set of measurable figures of merit and corresponding test procedures that were devised by the authors to support a panoramic sensor specification are introduced. The figures of merit, replacing conventional resolution, sensitivity and pointing accuracy mapping concepts are suggested and explained as viable alternative to the analogous imaging sensors measurement concepts.
