MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051119 A) filed by Indian Institute Of Information Technology Design and Manufacturing, Kurnool, Andhra Pradesh, on April 22, for '360-degree real-time electronic support and electronic countermeasure system for electronic warfare and a method thereof.'
Inventor(s) include Dr. K. Krishna Naik.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an integrated electronic warfare system combining Electronic Support Measures (ESM) and Electronic Countermeasures (ECM) in a single unified platform for 360-degree real-time signal detection and jamming operations. The system comprises a dual concentric circular antenna array architecture wherein an inner circular antenna array (106) of eight omnidirectional antennas functions as receivers for capturing incoming electromagnetic signals, while an outer circular antenna array (102) of eight antennas functions as transmitters for radiating countermeasure signals. A rotational sensing mechanism with a stepper motor (110) controlled by a microcontroller (112) enables sequential scanning of antenna elements for enhanced angular resolution. The system (100) employs direction-of-arrival estimation using multi-parameter analysis combining amplitude, phase, and frequency measurements. A spectrum analyser (114) extracts signal parameters in real time, and a signal generator (104) produces adaptive countermeasure signals including broadband noise and modulated interference for jamming hostile transmissions."
