This contribution reports some of the fusion results from the EDA SNIPOD project, where different multisensor
configurations for sniper detection and localization have been studied. A project aim has been to cover the
whole time line from sniper transport and establishment to shot. To do so, different optical sensors with and
without laser illumination have been tested, as well as acoustic arrays and solid state projectile radar. A sensor
fusion node collects detections and background statistics from all sensors and employs hypothesis testing and
multisensor estimation programs to produce unified and reliable sniper alarms and accurate sniper localizations.
Operator interfaces that connect to the fusion node should be able to support both sniper countermeasures and
the guidance of personnel to safety. Although the integrated platform has not been actually built, sensors have
been evaluated at common field trials with military ammunitions in the caliber range 5.56 to 12.7 mm, and
at sniper distances up to 900 m. It is concluded that integrating complementary sensors for pre- and postshot
sniper detection in a common system with automatic detection and fusion will give superior performance,
compared to stand alone sensors. A practical system is most likely designed with a cost effective subset of
available complementary sensors.
This paper investigates the laser damage threshold under C.W. CO<SUB>2</SUB> laser irradiation. It has been already shown that the destruction of each mirror is characterized by a critical temperature: the mirror is destroyed when this temperature is reached. The aim of this paper is to compare the laser damage threshold and the critical temperature.
