VERA passive sensor

VERA -VERA passive radar (in Czech known as Věra) is an electronic support measures (ESM) system that uses measurements of time difference of arrival (TDOA) of pulses at three or four sites to accurately detect and track airborne emitters. It is reportedly able to detect military "invisible aircraft".
