ICST


Infrared Countermeasures Sensor Tester 
 
The Infrared Countermeasures Sensor Tester (ICST) simulates a realistic, dynamic scenario for sensor testing at the lab and depot level. In the scenario, the following components are controlled:

  The target’s position relative to the sensor
  The sensor’s rotational position
  The temperature of the IR source

The ICST is a modular test system that may be modified according to customer requirements.

System Components
The ICST includes three major assemblies:
  Sensor motion assembly
  Target motion assembly
  A controlled IR source
