Difference between Multilateration and VERA passive sensor

Multilateration vs. VERA passive sensor

Multilateration (MLAT) is a surveillance technique based on the measurement of the difference in distance to two stations at known locations by broadcast signals at known times. 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.

Electronic warfare support measures

In military telecommunications, the terms Electronic Support (ES) or Electronic Support Measures (ESM) describe the division of electronic warfare involving actions taken under direct control of an operational commander to detect, intercept, identify, locate, record, and/or analyze sources of radiated electromagnetic energy for the purposes of immediate threat recognition (such as warning that fire control RADAR has locked on a combat vehicle, ship, or aircraft) or longer-term operational planning.

Kopáč passive sensor

Kopáč (the word means "digger" in Czech) was an early electronic warfare support measures (ESM) system developed in Czechoslovakia in the early 1960s that used measurements of time difference of arrival (TDOA) of pulses at three sites to accurately detect and track airborne emitters.

Line-of-sight propagation

Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver.

Ramona passive sensor

Ramona was the second generation Czechoslovak 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.

Secondary surveillance radar

Secondary surveillance radar (SSR)Secondary Surveillance Radar, Stevens M.C. Artech House, is a radar system used in air traffic control (ATC), that not only detects and measures the position of aircraft, i.e. bearing and distance, but also requests additional information from the aircraft itself such as its identity and altitude.

Tamara passive sensor

Tamara was the third generation Czechoslovak electronic support measures (ESM) system that used measurements of time difference of arrival (TDOA) of pulses at three or four sites to accurately detect and track airborne emitters by multilateration.
