“…The first important parameter is spectral emissivity

in Equation ( 2 ). The normal temperature of combusted CO 2 gas from ships is approximately 600 K by infrared signature suppression (IRSS) [ 44 ]. The emission band-width of CO 2 gas is proportional to the temperature of the CO 2 gas [ 39 ].…”

Infrared ship-target detection for sea surveillance from the coast is very challenging because of strong background clutter, such as cloud and sea glint. Conventional approaches utilize either spatial or temporal information to reduce false positives. This paper proposes a completely different approach, called carbon dioxide-double spike (CO2-DS) detection in midwave spectral imaging. The proposed CO2-DS is based on the spectral feature where a hot CO2 emission band is broader than that which is absorbed by normal atmospheric CO2, which generates CO2-double spikes. A directional-mean subtraction filter (D-MSF) detects each CO2 spike, and final targets are detected by joint analysis of both types of detection. The most important property of CO2-DS detection is that it generates an extremely low number of false positive caused by background clutter. Only the hot CO2 spike of a ship plume can penetrate atmosphere, and furthermore, there are only ship CO2 plume signatures in the double spikes of different spectral bands. Experimental results using midwave Fourier transform infrared (FTIR) in a remote sea environment validate the extreme robustness of the proposed ship-target detection.

This paper presents a single numerical performance characteristic for the evaluation of seeker tracking algorithms. It concentrates on ship IR seeker tracking algorithms. Assessing the threat from guided missiles needs a sound evaluation of their performance. The main goal is to introduce a characteristic which is able to assess the threat for ships depending on various scenario parameters. It is shown that for these applications such a single characteristic is sufficient. In order to achieve this five popular tracking algorithms are used. Synthetic IR image sequences are generated to simulate a large set of attack approaches and assemble sufficient statistics on the behavior of the algorithms. The introduced characteristic can also be used for investigations on algorithms themselves, e.g. for sensitivity analyses and parameter optimization of a single algorithm, and for comparison of different algorithms

“…Examples are given in Figure 3 in the case of maritime scenario. The direct exploitations of such outputs have been proven useful for external applications such as a target acquisition model in the EO-VISTA software framework (see Bijl et al, 2008) [1] or a complete missile fly-out simulator with the TNO Electronic Warfare Model EWM (see the hit point analysis by Schoemaker et al, 2010) [8] . However this type of coupling was limiting since the applications were forced to consider open loop simulations and prevented more advanced studies on dynamic scenarios.…”

“…For a couple of projects, IR imaging seeker models have been implemented and tested in house either on real data (SURFER project, see Broek et al (2000) [2] ) or simulated data from a very modest scene generator (see the countermeasure methodology presented by Schoemaker et al (2010)) [8] .…”

Modern infrared imaging seekers can nowadays deal with higher resolution and less noisy sensor images. The testing of new image processing or tracking algorithms requires a fitted set of relevant sensor images. When no actual recordings are available, when experimental benches are not adapted or at an early stage of development, one can require a simulation tool to generate synthetic infrared sensor images. This paper presents the first version of ISISserver (Infrared Sensor Image Simulation Server) a software library developed at TNO and used for infrared (IR) imaging seeker applications. Based on the EOSTAR Pro (Electro-Optical Signal Transmission And Ranging) model suite, the set of functions offered by this toolkit allows analysis of synthetic sensor images generated for various synthetic environments and targets. Typical targets from a database can be used as well as externally user designed 3D targets. Simulation results using ISISserver toolkit with test data (not realistic or physical data) will be shown.
