The system considered in the analyses consists of four sensors and associated receiver... The VERA passive radar (known as Věra in Czech) 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". The manufacturer is ERA a.s. [cz], based in Pardubice.
