An ultra-wide Field staring infrared detection system is introduced for high valuable instruments protection. First
the presentation will cover the basic design principles and hardware structure to understand how the system is working,
which base on real-time processing. For wide-field and high sensitivity induce high false alarm, the problem is
essentially to detect moving point-like targets submerge in abundant background noises. Balance high repetition rate and
sensitivity, a simple detect algorithm is introduced. For less spatial target space information can be used, an improved
interactive track algorithm is proposed. The characteristic of targets correlation between sequences can be used to reduce
system false alarm. Results of basic ground based test are presented. These kinds of system have vast application
possibilities such as airborne and maritime platform to surveillance and guidance.
