Electro-optical and Radar Sensors in Verification
Telemetry intelligence on a missile test is frequently combined with electro-optical intelligence and radar tracking from cameras on aircraft (e.g., US RC-135 COBRA BALL), ground stations (e.g., US COBRA DANE) and ships (e.g., US COBRA JUDY). Observed trajectories, speeds, etc., can be used to verify the TELINT information is accurate. Even though some of these techniques do take pictures, these, as a whole, are considered MASINT
Methods continue to evolve. COBRA JUDY is intended to gather information on long-range missiles, in a strategic role. One developmental system, COBRA GEMINI, is intended to complement COBRA JUDY. It can be used for observing long-range missiles, but is also appropriate for theater-level weapons, which may be addressed in regional arms limitation agreements, such as the Missile Technology Control Regime (MCTR). Where COBRA JUDY is built into a ship, this dual frequency (S- and X-band) radar is transportable, capable of operating on ships or on land, and optimized for monitoring medium range ballistic missiles and antimissile systems. It is air-transportable to deal with sudden monitoring contingencies.

Famous quotes containing the words radar and/or verification:
“So I begin to understand why my mother’s radar is so sensitive to criticism. She still treads the well-worn ruts of her youth, when her impression of mother was of a woman hard to please, frequently negative, and rarely satisfied with anyone—least of all herself.”
—Melinda M. Marshall (20th century)
“Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.”
—Rudolf Carnap (1891–1970)
