Simulate Multiple Radar Targets and EW Jamming Threats

Verifying radar systems during live flights in range testing is not only expensive but introduces uncertainty through the inability to control the environment. Utilizing a radar environment simulator addresses these issues and ensures that your radar system is prepared to achieve success under the most challenging operating conditions.

Radar environment simulators that also model electronic attack threats and ground reflections provide a level of testing confidence required for advanced radar programs. At Mercury, we leverage our experience developing DRFM-based electronic attack training solutions to provide a fully customized product with a validated threat library to emulate the most complex jamming and deception techniques.

Modular and Scalable

Do you need a benchtop system for creating simple targets or do you need a multi-channel solution for complex radar testing in an anechoic chamber?

Since every new program is unique, a flexible radar environment simulation solution is required. At Mercury we develop our simulators around a modular DRFM architecture that can be scaled to increase the channel count or capability set.
