Surveillance image denial verification
First Claim
1. A countermeasure system, for use against a satellite imaging system configured to transmit telemetry communications comprising image data obtained using an imaging sensor, the countermeasure system comprising:
- a laser light source configured to illuminate the imaging sensor of the satellite imaging system with laser light;
a modulator configured to modulate the laser light to inject a pattern into the image data generated during an operation of the satellite imaging system;
a telemetry receiver configured to intercept telemetry communications comprising the pattern-injected image data and transmitted from the satellite imaging system; and
an analyzer configured to analyze the pattern-injected image data in the intercepted telemetry communications to determine at least one characteristic of the satellite imaging system utilizing at least one parameter of the modulated laser light and/or to determine an effectiveness of the laser light source in inhibiting the operation of the satellite imaging system.

Abstract
An assessment method and system for characterizing the operation of an imaging system are disclosed. The assessment system can comprise a light source configured to illuminate the imaging system, a modulator configured to modulate light from the light source, a receiver configured to intercept communications from the imaging system, and an analyzer configured to analyze the intercepted communications. The assessment system can be used to determine the effectiveness of an image denial system that is used to prevent a surveillance satellite from providing imagery and can thereby provide an advantage on the battlefield.
