Wideband electronic reconnaissance and localization in jamming environment

Time Difference Of Arrival (TDOA) method is very often used inside electronic intelligence systems. TDOA method requires the high signal to noise ratio at the output of the intermediate frequency amplifier for target localization, usually around 12 dB or more. At low signal-to-noise ratio TDOA is inaccurate and especially in case of the active jamming it is nearly impossible. The multilateral TDOA electronic inteligence system concept and design, which enables to locate and to pursue the targets in case of low signal to noise ratio, is proposed in the paper. The proposed system offers good performance especially in the presence of an active noise jamming.
