The ESM/ELINT Receiver is a compact, high-speed electronic support system developed to intercept, analyze, and characterize radar emissions across the 2–18 GHz frequency range. Equipped with four RF input channels, it provides direction-finding capability while generating Pulse Description Words (PDWs) in real time, including frequency, amplitude, pulse width, time of arrival, and Pulse Repetition Interval (PRI). The integrated signal processor supports output of more than two million PDWs per second, with data transmitted via Gigabit Ethernet and telemetry handled through LVDS.
Designed for low-SWaP deployment, the receiver incorporates Digital Frequency Discriminator (DFD) and Successive Detection Log Video Amplifier (SDLVA) blocks to enable high-precision signal detection. Built-in digital filtering and channel-selective switch-multiplexer filters reduce unwanted signals and mitigate interference, supporting reliable operation in dense electromagnetic environments.
The system is engineered for integration across compact defense platforms operating in land, maritime, and airborne roles, where space and power constraints are critical. Its performance characteristics support electronic support measures (ESM) and electronic intelligence (ELINT) tasks, including radar signal monitoring, threat detection, and situational awareness.
Built to meet MIL-STD-810G and MIL-STD-461F standards, the receiver delivers high sensitivity and wide instantaneous bandwidth, supporting deployment in demanding operational conditions across intelligence, surveillance, and electronic warfare applications.
