[edit] systems of passive radar

Is pps-vera-E a passive radar system?

note that the term "passive radar" is also sometimes incorrectly used in the popular press to describe passive RF sensors that detect and track aircraft by the aircraft's own RF emissions (such as radar, communications, or transponder emissions). These systems are more accurately described as ESM systems using time difference of arrival (multilateration) or triangulation processing to locate targets. Well known examples include the Czech Tamara and VERA systems, as well as the Ukrainian Kolchuga system.

I'll qoute from the manufacture's site:

PSS VERA-E, The state of the art mobile PSS VERA-E is an ELINT and Passive Surveillance System designed for location, identification and tracking of air, ground and naval (ship) targets. PSS VERA-E is based on the well proven passive Time Difference Of Arrival (TDOA) multilateration technique using signals of air, ground and naval radar, jammer, SSR transponder, TACAN/DME, interrogator, DataLink and other pulse emitters. Besides ELINT missions, PSS VERA-E is extremely suitable as a passive surveillance sensor in air defence systems. The PSS VERA-E uniquely merges ELINT features together with high quality surveillance features (tracking of targets) provided so far only by active radar.

Are they refering to passive radar or only ELINT? --maayan 22:36, 15 May 2005 (UTC)

VERA is an ESM system only. It doesn't exploit reflections of signals, which is the defining characteristic of a radar. -- Paul Howland, 18 Sept 05
