Ramona passive sensor : ウィキペディア英語版 | Ramona passive sensor Ramona was the second generation Czechoslovakian 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 by multilateration. ==History== Ramona's designation was KRTP-81 and it carried the NATO reporting name of Soft Ball. The serial number was derived from the Czech phrase "Komplet Radiotechnického Průzkumu" meaning "Radiotechnical Reconnaissance Set". A later upgraded version was designated KRTP-81M. Ramona was deployed in 1979 and could semi-automatically track 20 targets simultaneously. It superseded Kopáč.
