ABSTRACT:
A detection system will detect and identify self-propelled objects, such as missiles, which create a hot exhaust plume. The exhaust plume has radiation which modulates with a frequency range of interest. This frequency range can be detected with various detectors, such as an infrared detector, an ultraviolet detector, or even a radio frequency detector. Guided missiles have radiation frequencies which are much higher than the radiation frequencies of jet aircraft and of reciprocating engines. A filter will filter the output signals from the detector, and discard those outside of the frequency range of interest. A warning signal will indicate if frequencies are encountered within the frequency range of interest.
