| 摘要 |
<p>The invention comprises a method of detecting a threat from a potassium-based munition in a section of monitored terrain, comprising:
collecting first light originating from a flash from a potassium-based munition using a collection optical system having a field of view;
intensifying the collected first light to form first intensified light;
detecting on a first position-sensing photodiode (PSD) a first intensified light spot formed from the first intensified light and converting the detected first intensified light spot into a first electrical signal; monitoring with a second PSD second light that does not come from the potassium-based munition and that is collected by the collection optical system, and providing a second electrical signal from the second PSD; comparing the first and second electrical signals to determine whether the detected first intensified light spot represents a threat from the potassium-based munition; and locating the threat within the field of view of the collection optical system.</p> |
