More advanced electro-optical systems can detect missile launches automatically from the distinct thermal emissions of a missile's rocket motor.

Plummer focused on developing the second generation of U.S. satellites - the electro-optical systems.

Still, there is renewed interest in both acoustic and electro-optical systems to complement counterartillery radar.

Their sensors - laser, electro-optical and infrared systems - could not see clearly through clouds, rain, fog, smoke or high humidity, it said.

The manufacturer of electro-optical systems remains a favorite even though it has more than tripled this year.

Corneal applanation is detected via an electro-optical system.

Just like acoustic based systems, electro-optical systems can generally be degraded by specialized suppression devices that minimize their sound or optical signatures.

In addition, the aircraft will carry multi-spectral electro-optical systems.

The fire control systems mainly consisted of radar and electro-optical system.

Once the target is acquired by radar, it is passed to the electro-optical system for tracking and engagement.
