Selex ES is an international electronics and information technology business, which is part of Finmeccanica S.p.A. It is based in Italy and the UK, and was formed in January 2013, following Finmeccanica's decision to combine its existing SELEX Galileo, SELEX Elsag and SELEX Sistemi Integrati businesses. It is organised into three divisions: Airborne and Space Systems, Land and Naval Systems, and Security and Smart Systems. Wikipedia.

A target detection apparatus is described that is capable of improved detection of targets in urban environments or hidden in cluttered environments. The apparatus emits radiation in a modulated fashion, of a known wavelength, wavelengths or range of wavelengths and detects radiation returned by the targets in the environment.

A system and method of reducing undesirable image artefacts such as image tear and image smearing are described. The system can include a series of pixels and enhanced sensitivity circuits. The circuit can be configured so as to operate in an enhanced sensitivity mode having a combination of sample and hold circuits and binning functions, the combination acting so as to reduce the undesirable imaging artefacts.

A method of forming infra red detector arrays is described, starting with the manufacture of a wafer. The wafer is formed from a GaAs or GaAs/Si substrate having CMT deposited thereon by MOVPE. The CMT deposited can include a number of layers of differing composition, the composition being controlled during the MOVPE process and being dependent on the thickness of the layer deposited. A CdTe buffer layer can aid deposition of the CMT on the substrate. Once the wafer is formed, the buffer layer, an etch stop layer and any intervening layers can be etched away leaving a wafer suitable for further processing into an infra red detector.

A system and method are described for detecting toxic gas releases in an urban environment. The system includes a series of repositionable remote sensor nodes that are located in an environment containing a toxic gas, the sensor nodes including a chemical sensor and/or a meteorological sensor. The sensor nodes gather data relating to the type of gas released and the surrounding atmospheric conditions and relay the information back to a data processing hub where the data is collated and analysed to produce an indication of the likely spread of the gas plume, the likely danger to the surrounding population and an indication of the release point of the gas.

An infrared detector system is described in which a despeckle filter is applied to image data generated by a High Operating Temperature (HOT) detector array. The filter reads the data associated with each pixel of the image generated and compares it with selected neighbouring pixels. The comparison yields a series of values that are compared to predetermined thresholds and the pixel is scored according to the number of values that exceed the threshold set. The score assigned to the pixel then determines the treatment of the pixel in the image to be generated. The data value of the pixel may be ignored, included or substituted with an alternative calculated value.
