OBJECTIVE: Develop and build a portable Real Time Electronic Warfare Receiver Surrogate (RTERS) prototype with a set of hardware, firmware and software of a simulated EW radar receiver and display to show the effects of the countermeasure techniques. DESCRIPTION: Battle damage assessment of Non-U.S. EW systems are hard to come by for the evaluation of the effectiveness of U.S. Electronic Attacks (EA) signals of an airborne EW system in a real time scenario. EW receiver surrogates are available to display normal radar signals on a Plan Position Indicator (PPI) but it cannot display the real time effects under the influence of EW techniques. The RTERS will evaluate EW techniques and Electronic Intelligence (ELINT) information as a surrogate radar receiver system when non-U.S. threat systems are not available. The RTERS prototype shall perform two major functions. The RTERS shall able to receive the proper signals of a CW, modulated waveforms and pulse radar information and stored these parameters in the prototype for comparison with the configured parameters in real time. The simulated radar display shall include the range and target indication display with regular radar signals. The second function shall show the effects on the simulated PPI when countermeasure signals are presented at the RTERS antenna inputs. The PPI shall display the EA effects on the simulated receiver display based on the EA techniques, dynamic changes in real time and the signal parameters that caused the effects are also overlaid on the same display in real time simultaneously. The RTERS prototype shall include but not limited to the ability to receive, process and display radar signals from L, S, C, X and Ku bands. The usage of Commercial-Off-The-Shelf (COTS) Software Define Receiver (SDR) and portable real-time spectrum analyzer & monitoring receiver instrumentation for prototype design are encouraged to minimize lengthy RF circuits and RF subsystem designs. The prototype shall have the capability to accept and to process the Red hawk framework plug-ins and RaptorX framework plug-ins to demonstrate developed applications. The prototype physical configuration shall include but not limited to a receiver/ processor, a display, a mouse, a keyboard, and a Double Layer DVD RW drive to perform command, control, data exchange and data storage of the RTERS system. For operation security, the prototype memories of the system shall be accessible and removable from the front panel of the system. Once the memories of the system are removed, RTERS shall be inoperable. No data, firmware and software can be retrieved from the RTERS prototype. The total system weight shall be less than 25 lbs. The system shall operate on a 120 volts AC household outlet. The prototype receiver system shall include multiband antennas to receive the required radar frequency band signals. The antennas shall have a 360 degree field of view. The antenna subsystem shall able to scan 360 degrees continuously through mechanical and/ or electronic means to receive the proper radar signals. When the prototype system operates in synchronized mode with the simulated emitter, the prototype receiver system shall able to switch off the receiver antennas function during simulated emitter transmission period to a avoid co-site interference or high power transmitted signals damage to the receiver. For demonstration in an anechoic chamber, the prototype receiver is outside of the anechoic chamber. The antennas are placed inside the chamber, the cable separation could be as long as 25 feet from the receiver. Compensation of the signals are required to avoid signal power losses over the cables. The prototype receiver shall have the capability to process incoming radar signals and countermeasure signals continuously. The prototype system shall able to store 10 seconds or more of real time signals with a bandwidth of 500MHz or wider bandwidth signals. The stored signals shall be labeled for data retrieval in real time. The porotype system shall provide demodulated In-phase and Quadrature component (I/Q ) digital signals for external RF recording. The RTERS prototype shall have the interfaces to synchronize with GPS timing and external emitter simulator timing to perform real time operation. The prototype shall able to operate with Low-Voltage Differential signaling (LVDS) interface to connect to real time RF recorder for events recording. The system shall have Display Port interface connector and High-Definition Multimedia Interface (HDMI) connectors for external secondary display. The system interface shall have Secure Digital (SD) memory slot for down load and revise of configuration profile of 128 Gigabytes (GB) of data and files. The prototype system shall able to network through Bluetooth, Gigabit Ethernet interface and regular Local Area Network (LAN) interface. PHASE I: The Phase I RTERS prototype system development shall provide the following results in a report: i. Identify and define the technologies, COTS systems and components that could support the design and built the RTERS prototype. ii. Provide a concept hardware, firmware and software design of the RTERS prototype system. iii. Perform an analysis of the system performance iv. Provide the outline feasibility of producing a demonstration of RTERS in phase II, and will outline demonstration success criteria in Phase II PHASE II: The Phase II program shall continue with the phase I concept to design and fabricate RTERS prototype system for a successful demonstration of the system requirements. The phase II program shall include: i. Develop, demonstrate, and validate the RTERS design concept of Phase I ii. Implement the best approach from Phase I into hardware and software system iii. Establish performance parameters through experiments and prototype fabrication iv. Develop, test, and demonstrate the prototype design v. Define field test objectives and conduct limited lab testing vi. Construct and demonstrate the operation of the RTERS prototype vii. Demonstrate the prototype in accordance with the test objectives viii. Provide a monthly report with detailed technical progress and program expenses ix. Provide a plan for practical deployment of the proposed commercial applications PHASE III DUAL USE APPLICATIONS: Phase III of the prototype system will be oriented towards technology transition to Acquisition Programs of Record and/or commercialization of the technology. In Phase III, the contractor is expected to obtain funding from non-SBIR government sources and/or the private sector to develop or transition the prototype into a viable product or service for sale in the military or private sector markets.
