SRC is a nationally recognized leader in the development and manufacture of radar systems and radar technologies for the US DOD and other government agencies. Radar related development at SRC encompasses the following three areas:

• Radar Systems Development and Manufacturing
• Radar Technology Development
• Radar Modeling, Simulation and Analysis

Radar Systems Development
SRC has extensive experience in the development of all types of radar systems. These have included weapon location radars, battlefield surveillance radars, airborne GMTI and AMTI radars, bistatic and multi-static radars, foliage penetration radars, wide-band imaging radars, and lightweight man-portable radars. We have complete end-to-end radar system development, prototyping, manufacturing and logistic support capability in-house, and work closely with our customers and the system end-users to define system requirements, develop system concepts, and predict system performance.

Weapon Location Radars:
SRC has developed a series of weapon location radars providing precise launch point location of mortars, artillery and rockets. Weapon location radars developed by SRC range from large vehicle based systems to small lightweight portable systems, and include both monostatic and bistatic implementations.

Airborne Radars:
Monostatic and bistatic airborne radars have been developed by SRC for both AMTI and GMTI applications. These systems are designed for both manned and unmanned airborne platforms.

Battlefield Surveillance Radar:
Manportable battlefield radar systems have been developed by SRC for detection and tracking of ground vehicles, personnel and helicopters. A complete electronics upgrade to the AN/PPS-5 battlefield surveillance radar system was developed and fielded by SRC for the US Army. The AN/PPS-5D provides dramatic improvements in performance and reliability while reducing weight and power consumption.

Radar Technology Development
Advanced radar technology development is on-going at SRC in areas including digital signal processing, antennas, receivers, digital beamforming, adaptive processing techniques and real-time software.

Antenna Technology:
SRC designed, developed, built and tested many phased-array antennas from VHF through X-Band. SRC has vast experience in designing phased array antenna elements, microwave beamformers, and electronic switches to provide optimum performance over wide steering angles. Recently, SRC has been developing antennas for airborne platforms that utilize Space-Time Adaptive Processing (STAP) for jammer and clutter cancellation.

Receiver Technology:
Over the past 40 years, SRC has designed, developed, and tested a multitude of microwave receivers from HF through Ka-band. Currently, SRC is developing receivers to support a number of radar programs, including several multi-channel systems that require precision channel-to-channel amplitude and phase matching to support adaptive jammer and clutter cancellation.

Digital Signal Processing Technology:
Digital signal processing has always been a cornerstone of SRC radar development. Over the past 20 years SRC has developed and tested five generations of radar digital signal processors. Our current DSP provides over 20 GOPS on a single 6U VME card. We are in the process of designing our 6th generation DSP that will provide over 200 GOPS on a single 6U VME card with more than 5 Gbytes per second of I/O bandwidth.

Real-Time Embedded Software:
Real-time embedded software development requires software engineers that understand the interaction of hardware and software as well as the importance of algorithm optimization, task scheduling and prioritization, and interprocess communication. SRC software engineers are very experienced at developing real-time embedded software solutions and have been integral players in the successful execution of a multitude of radar and communication system development programs. Our software domain expertise includes real-time control, multiple target trackers, target discrimination and ID, ballistic and non-ballistic trajectory estimation, and GUI design.

Space-Time Adaptive Processing (STAP):
SRC has extensive expertise in STAP and has been investigating the general problem of STAP for many years. Under a recent Independent Research and Development program, SRC has developed a variant of the basic PAMF formulation and applied it to several available data sets, both simulated and real, with excellent success.

Radar Modeling, Simulation and Analysis
SRC has developed and utilizes detailed modeling and simulation tools to predict the performance of radar systems before they are developed. Virtual experiments can be run, and data collected, years before the actual systems are deployed, reducing the costs and risks associated with system development.

During system testing, the virtual data can be compared to the actual data collected to quickly identify the system problems, test problems and to validate system performance. Data from SRC’s modeling and simulation tools can then be used to extrapolate performance in different environments and evaluate the performance affects of proposed design changes.

The Multi-Int Simulation Technology (MIST) developed by SRC is currently being used by both the Government and industry to run virtual experiments and collect data for systems that won’t be deployed for many years. The data from MIST is helping to reduce risk in:

• Space and Airborne Radar Programs
• Space and Airborne Sensor Integration
• Multi-static and Bistatic radar
• Adaptive processing techniques
• Sensor development and testing

SRC has also produced many complete radar and communication system models using MATLAB. Many of these models have been validated using real radar data collected in various radar testbeds. Complex receive and transmit antenna systems are evaluated against different jamming threats. Internally developed radar simulation programs are used to determine radar performance in the presence of ground clutter and masking.
