ECM/TSKOR Electronics provides base-band to W band ECM/TS to U.S. and foreign customers. KOR Electronics ECM/TS allow the user to produce a wide variety of customer provided ECM techniques. ECM/TS are provided with menu driven GUI interface for ease of technique definition and control. Fast technique switching continues to be a KOR Electronics competitive advantage. Applications include: radar crew training during free-space simulations, ECM vulnerability and ECCM effectiveness testing in either the laboratory or in an anechoic chamber or test range.

Specifications

The family of simulation products designed by KOR Electronics includes a versatile, high performance, Electronic Counter Measure and Target Simulator (ECM/TS) system. The heart of this system consists of our ultra-wide-band and spectrally clean multi-bit digital RF memories (DRFMs) that are based on industry standard VMEbus architecture.

The ECM/TS system can be configured to utilize from 1 to all 8 bits.These DRFMs are ideal for target return generation, as well as, the simulation of coherent jammers of various fidelities. By including optional ECM technique generation software, KOR Electronics can provide a complete, cost effective, and flexible ECM and Target Simulator system for your laboratory, anechoic chamber, or free-space radar and seeker testing requirements.

As with other products in the KOR Electronics RES family, these simulators receive/process target geometries and in-beam calculations in real-time. Since the transmitted waveform is stored and recalled by the DRFM, it is not necessary to be connected to the radar to determine pulse/dwell characteristics.

This allows the system to be used for testing many different radars and seekers without designing new interface hardware and software. Target return fidelity can be further enhanced to include Doppler modulation, Amplitude Control (Range, RCS, and Scintillation), as well as, radar signal modulations (JEM, RSM). In addition to coherent deceptive techniques, the ECM/TS can be configured to simulate a wide variety of CW and noise jamming techniques. The Block Diagram tab shows a typical ECM/TS.

The Host Computer is a Pentium based IBM PC compatible computer that hosts the RES graphical user interface software package designed by KOR Electronics for developing and monitoring scenarios, as well as, performing all maintenance functions (like Built-In-Test and Calibration). The Graphical User Interface (GUI) allows the operator to develop scenarios and ECM techniques with minimal effort utilizing libraries of components ranging from ECM definitions to target trajectories. The operator is provided the ultimate in control and flexibility via user definable tables (UDT) for entering or modifying data files stored in these libraries.

The RES Host provides the ability to monitor scenario progress, including target positions, current ECM technique, and select platform data. The ability to remove targets/jammers from the scenario, or re-activate them later is also provided. System commands like Run, Freeze, Resume, and Stop are provided to the operator for execution control.

For real-time simulation, the RES VMEbus architecture provides an industry standard, high speed, and modular approach to support the most sophisticated radar systems.

This architecture is ideal for interfacing with external scenario generators and controllers, adding additional system capabilities, and upgrading system performance through advancements in microprocessor and digital signal processing (DSP) technology. These systems are easily expandable to grow as customer requirements change over the life cycle of their radar program and test facilities. The IF/RF generation circuitry is the product of a long evolution of high performance simulator design that provides a custom yet modular approach to expand operation to additional frequency bands. This flexibility and experience, coupled with our advanced DRFM technology, has allowed KOR Electronics to be a leading supplier of free space ECM and Target Simulator systems covering base-band up to 100 GHz. The Specifications tab defines the performance of our ECM/TS products that we have delivered to customers around the world. Since all radars and their associated ECCM testing requirements are different, KOR Electronics is prepared to offer a solution customized to best meet your technical, cost, and schedule constraints.
