Abstract
The present invention relates to a thermal vision countermeasure system to enable concealment of objects from identification by thermal imaging night vision systems, including a screen made of thermoelectric modules, disposed between the target object and an IR detector. The screen, formed of at least one thermoelectric unit, is coupled to the target object, and the thermoelectric unit includes a Thermoelectric Cooler (TEC) module coupled to a plate formed of a material selected from aluminum, copper, or aluminum with copper, the plate being substantially larger than the TEC module.
Claims25
An infrared detection countermeasure system for a target object, the system comprising:
- a screen, formed of at least one thermoelectric unit, couplable to a target object;
- said thermoelectric unit including a TEC module coupled to a plate formed of a material selected from aluminum, copper, or aluminum with copper, said plate being substantially larger than said TEC module.
An infrared detection countermeasure system comprising:
- a screen, formed of a plurality of thermoelectric units, couplable to a target object;
- a controller for controlling, individually, said thermoelectric units;
- a plurality of thermal signatures accessible by said controller;
- a temperature sensor for measuring temperature of one side of said thermoelectric module and providing an indication thereof to said controller;
- and
- a power source coupled to each said thermoelectric unit;
- wherein said controller is coupled to said power source for causing said power source to provide a level of power, selected in accordance with a selected thermal signature selected from said database, to said thermoelectric units so as to generate a selected temperature in at least part of said screen to create said selected thermal signature.
A method for forming an infrared detection countermeasure system for a target object, the method comprising:
- forming a screen of at least one thermoelectric unit, couplable to a target object;
- forming said thermoelectric unit from a TEC module coupled to a plate formed of a material selected from aluminum, copper, or aluminum with copper, said plate being substantially larger than said TEC module.
