systems of passive radar
[edit]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
Developments in Czechoslovakia
[edit]This is a bad article. There is not even included developments in Czechoslovakia, which were developed for today has 4 generations of passive surveillance systems and the fifth is in progress. Czech passive surveillance systems are world leaders. Time hyperbolic principle was discovered in the late fifties and sixties, essentially simultaneously in the U.S., Great Britain, the USSR and Czechoslovakia. In Czechoslovakia, for example only Kopáč, Ramona, Tamara, Vera. Ukrainian Kolchuga you mentioned is almost exact copy of the Czechoslovak Tamara. Fifth generation of passive surveillance systems, Vera-NG, which is breakthrough technology PCL (Passive Coherent Location). It is a method for determining the position and those goals alone does not emit anything, and using external sources such as television networks or mobile phones. Any object is now, by moving, causing a deformation of these signals and creates specific reflections, which can be identified and monitored. Please update your article. —Preceding unsigned comment added by 88.103.99.163 (talk) 18:57, 17 February 2010 (UTC)
Integration time
[edit]This article and some about GPS and radio astronomy mention "integration time" but none discuss it in detail or even define it, far as I can see. Google turned up this which fails to illuminate my feeble understanding. An elementary, small explanatory article might help many casual readers of radio articles.
