MARK Resources, Inc. was founded in 1974, by several experienced engineers who wanted to establish a creative work environment for advancing state-of-the-art radar systems technology. Today, MARK Resources has a worldwide reputation for excellence in radar-related engineering R&D. Based in Torrance, California, USA, the company has built a team of productive professionals with unique qualifications and an exceptional record of achievement in three principal technical areas: radar signal processing, radar simulation, and radar systems.
MARK Resources has mounted a set of antennas, developed by Chelton, in an array on a specially designed frame, to meet the specific requirements for its new radar system.
The radar is officially called the High-Speed Target Acquisition and Tracking System (abbreviated as HSTAT system). It has been developed under the SBIR program with the US Air Force. It is designed to image and track multiple clustered objects. MARK Resources advise that the antenna array is working exactly as required.
Chelton designed the antennas and frame to guarantee that isolation between the C-Band transmit antenna and all five receive antennas was at least 70dB, thereby meeting its performance requirement specifications. The spacing between the antennas, combined with the 20 degree beam widths for each, ensured that this critical specification was met.
Chelton utilised its state-of-the-art anechoic test chamber, to test for high-level isolation with the utmost thoroughness.
