t he monitor news DARPA SOLICITS PROPOSALS FOR SIGNAL PROCESSING AT RF (SPAR) PROGRAM ARMY COMPLETES FIRST EWPMT CAPABILITY DROP The Army has completed the first capability drop of its new Electronic Warfare Planning and Management Tool (EWPMT). The planning and management component of the Integrated Electronic Warfare System (IEWS) capability set, EWPMT is intended to allow for greater management and control of the Electromagnetic Spectrum (EMS) and enhance current and future EW capabilities. The EWPMT is being developed and delivered in stages through four capability drops, planned at roughly 15-month intervals. According to LTC Marc Dorrer, Product Manager for Electronic Warfare is also intended to enable RF systems to perform simultaneous transmit and receive (STAR) at the same frequency, doubling spectrum efficiency. Performers will be expected to propose novel signal interferencemitigation technologies using analog signal processing techniques and chip-scale nonreciprocal component technology. To enable a functioning system with military capabilities, technical challenges include, but are not limited to: innovating enabling technology to mitigate the effects of in-band interferers; incorporating signal coding and correlation processing approaches; and meeting simultaneous program metrics of high linearity, low noise, processing gain, and input power with approaches that produce chip-scale components compatible with current integrated circuit fabrication processes. The program is organized into three Technical Areas (TAs). The goal of SPAR TA1 is to develop analog signal Integration (PdM EWI), who oversees EWPMT within the Army's Project Manager Electronic Warfare & Cyber (EW&C) office, the system will provide electronic warfare operators (EWOs) and spectrum managers (SMs) with an integrated tool to support maneuver commanders in planning, coordinating, synchronizing and executing Electromagnetic Spectrum Operations (EMSO). "EWPMT is an Electromagnetic Battle Management (EMBM) capability that will transform the way the EWO and SM coordinate, collaborate, synchronize, and share information within the command post to achieve 2/3/6 staff integration." processing elements operating at the RF front-ends of both the transmitter and receiver, enabling cancelation of self-interference and a 100-fold suppression of uncooperative in-band interference. TA2 will develop miniature nonreciprocal components, such as circulators, for directional routing of RF signals to achieve an additional 25 dB of transmitter suppression at the receiver. TA3 will demonstrate TA1 and TA2 component technologies, with system performance relevant to communications systems with STAR capability. Total funding for the program is projected to be $30 million broken down into $17 million for TA1, $8 million for TA2, and $5 million for TA3. Multiple awards are expected in each technical area. Proposals are due by May 12, and the scheduled start date for the program is October 1. The solicitation number is: DARPA-SN-16-20. The primary point of contact is Troy Olsson, e-mail: DARPASN-16-14@darpa.mil. - J. Haystead Developed under a contract with Raytheon Space and Airborne Systems, EWPMT Capability Drop One (CD 1) is specifically focused on EW operations and providing EWOs with automated EW mission planning, EW targeting, robust modeling and simulation to support visualization and characterization of the electronic order of battle (EOB), and the ability to generate EW messages, reports and requests. A successful operational test of the capability was completed in February. Follow-on CD 2 requirements have been approved by the Army and PdM EWI expects to start development on or about June 2016. According to Lieuten- The Journal of Electronic Defense | March 2016 The Defense Advanced Research Projects Agency (DARPA) Microsystems Technology Office (MTO) has released a BAA for the Signal Processing At RF (SPAR) program. The Agency held a Proposers Day for the program last month. The objective of the SPAR program is to develop radio frequency (RF) analog signal processing and nonreciprocal technology to mitigate in-band interference signals beyond what is possible with current approaches. The program aims to develop the underlying technologies to suppress non-cooperative in-band RF signals, as well as self-interference, directly at the antenna and prior to the RF receiver electronics, thereby significantly relaxing the dynamic range requirements for amplification, downconversion, digitization and digital signal processing in a typical receiver. The overall goal is to allow radio and radar operation in more congested and contested RF environments. SPAR 15
