MARK Resources: Radar Systems Technology

MARK Resources

MARK Resources was founded in 1974 to perform radar R&D. It has extensive and rather unique experience in several areas of radar systems technology, including the design, development, analysis and simulation of radar systems, and radar signal processing. This work is led by Drs. Richard Mitchell, August Rihaczek and Stephen Hershkowitz, who have collectively authored five books on radar. They are internationally recognized experts in radar, and all continue to remain very involved in the technical activities of the company. The company is at the vanguard of innovation, deriving novel solutions to some of the most challenging problems facing our military.

Radar Systems Design and Development

The company has done pioneering work in the formulation of systematic design procedures for high-performance radar that have been applied in a wide variety of ground-based, airborne and missile radar system designs, both for private companies and the Government. Until recently, however, our involvement was limited to "paper" designs. This changed dramatically as we developed a wideband radar system for White Sands Missile Range to be used for highly accurate measurements of miss distance and target attitude in test range applications. About half of our current business is in radar system development, including the following:

High-Resolution Instrumentation Radar: This coherent X-band system is a fully autonomous test range instrument. It employs a bandwidth of 1500 MHz, which is capable of a range resolution of 4". It is mounted on a trailer and remotely operated.

RF Imaging System: This X-band radar also employs a bandwidth of 1500 MHz. A second version of this system has also been developed.

High-Speed Target Acquisition and Tracking System: This non-scanning radar is designed to simultaneously detect and track multiple objects in the testing of a wide variety of military weapons.

Wave Measurement Radar: This X-band system is designed to measure wave conditions in the vicinity of a boat.

Compact Non-Scanning Radar: This low-power non-scanning radar is designed for eventual installation on small boats and submarines, for situation awarness.

CW Radar: This non-scanning radar is designed to detect and track multiple clustered objects (sub-munitions).

Radar Signal Processing

About half of MARK Resources' business is in radar signal processing, with applications to detection, discrimination, target identification and target motion and trajectory analysis. Innovative work in this area began in the early 1970s when we developed a new signal processing technology based on short-term sliding-window Fourier transform analysis, which we call Target Motion Resolution (TMR) processing. Since the early 1980s the company has also been actively engaged in development of a new Complex-Image Analysis technology, which has been applied to a wide variety of problems related to target discrimination, classification and identification.

Radar Simulation

MARK Resources has considerable experience in the simulation of radar signals and systems. The company's involvement in real-time simulation goes back to the early 1970s when it developed the basic concepts for simulating extended targets and distributed clutter. Since then, we have developed several computer-based systems to simulate target and clutter signals for input in real time to airborne radars under test. We have also developed numerous large-scale programs for simulating all types of target and clutter environments seen by practically every type of radar.


As a small technical organization, MARK Resources can respond immediately to its customers' needs. The company has earned a reputation for developing ingenious practical solutions to a wide variety of difficult problems in radar design, simulation, signal processing and target identification. We would love to hear about your technical problems if they are related to these areas.
