Diarcy Technologies

Diarcy Technologies is an engineering services firm with extensive experience in military/defense applications. We have over 20 years of experience working with defense contracts, providing a full range of services including electronic product design and build, hardware enhancement and re-design, system integration, software design, training and consulting. We are an outsource resource for military electronic product manufacturers seeking extremely high-tech design assistance.

Our focus is on helping our clients lower their risk by providing expertise in product design and development, resulting in an accelerated time-to-market for their product announcement and delivery. We accomplish this by being a "flex-force" technical resource that can come in, do the technical work, and get out fast so they can meet their overall project schedules, and create a product with superior technology than the competition. A partial list of our capabilities is listed below. You are encouraged to contact us to discuss your application.

F-18 Aircraft

Laboratory Radar Simulators

We have designed laboratory radar signal simulators for testing electronic warfare systems. These systems produce low-power modulated RF signals to be used as signal sources for testing electronic warfare systems in a laboratory environment. These signals can also include interference and jamming signals to better simulate real world conditions.

Antenna Design

Complementing our emitter and active decoy capabilities, we have expertise in antenna design for all applications. For receiver and lower-powered transmitter applications, printed or wire-type geometries are recommended. For higher-powered transmitter applications, waveguide/horn geometries become the antennas of choice. When needed, we use advanced computational techniques to aid in the antenna design. Our expertise in this area will ensure that your entire electronic warfare system will perform to your specifications.
