Location Jamming of Radar Waves Using Software-Defined Radio

Nowadays, radar plays a key role in the world of warfare. The detection of critical military assets of the enemy is a must nowadays in modern warfare in order to cripple the enemy. However, the use of radar and electronic warfare (EW) in general has also given rise to Electronic Countermeasures (ECMs) or jamming to counter radar detection and protect these assets. One such method involves deceiving the non-cooperative source (NCS) by sending pulses so as to obscure the location of the targeted asset. In this paper, we propose using Software-Defined Radio (SDR) technology to first detect radar signals of the NCS, estimate the range of the source, and calculate the angle of impact of the radar on the listening antenna to estimate the position of the NCS. Once we get the mentioned factors, the SDR will transmit pulse waves to estimated location of the NCS and attempt to provide false information regarding the location of the intended target.
