6 Synthetic aperture radar uses electronics to vary the nature of the virtual aperture of a radar detector, so that a single instrument can be made to mimic a range of instruments.

The range of the rocket is over 31km and at mid range produces a dispersal pattern similar to those quoted above.

The precise range and range rate equipment (PRARE), operational on ERS 2, allows precise orbit calculations to be made and accurate corrections to radar altimeter measurements to be implemented.

For instance, I took them skiing in the Mid Atlantic Range, which is this range of mountains in the middle of the Atlantic.

We're going to look at the mid ocean ridge, a 40,000 mile long mountain range.

The mid ocean ridge is a huge mountain range, 40,000 miles long, snaking around the entire globe.

Their use is systematically based on a range of capabilities for command, target acquisition (radar units, observers, drones, etc.) and means of delivery (launchers).

11. The principal instruments on board the satellites include (a) an Active Microwave Instrument (AMI), which comprises a synthetic aperture radar (SAR) and a wind scatterometer (b) a radar altimeter (RA) (c) an along track scanning radiometer (ATSR), which comprises an infrared radiometer (IRR) and a microwave sounder (MWS) (d) precise range and range rate equipment (PRARE), presently functioning only on ERS 2 and (e) a laser retroreflector.

15. Radar remote sensing from space has a number of advantages over airborne radar.

In addition, to clarify comments in paragraph 609, it should be emphasized that examinations are never conducted for candidates from countries within range (above mid point).

They're not on my radar.

Denmark has deployed a temporary solution by providing a radar to enhance situational awareness for controllers at Kabul International Airport, although this radar will need to be replaced by a permanent civilian air traffic control certified radar.

It really wasn't on the radar screen.

It completely passes below the radar screen.

The dense spatial samplings (100 pixels sq km) provided by radar interferometry in the detection of displacements associated with its accuracy (in the range of 3 10 mm) make it an important tool for assessing most natural hazards.

The Department of Peacekeeping Operations is intensively testing radar imagery and works with its system contractor RADARSAT International to evaluate higher resolution digital elevation model generation from radar imagery, as well as using radar imagery for mapping purposes.

Materials of varying roughness a factor which is dependent on the particular radar wavelength being used reflect the radar signal in different ways.

Knowledge of radar image interpretation is becoming increasingly important because of the growing number of operational and planned radar satellites (e.g. ERS 1, ERS 2, JERS 1, Radarsat) and the attendant increasing use of spaceborne radar as a tool to monitor tropical regions.

ERS 1 radar altimeter data provide worldwide surface information.

It is different from optical sensors in that it operates within a frequency range, designated C band, at a nominal frequency of 5.3 GHz with vertical transmission and vertical reception of radar signals (VV polarization) and a look angle of 23 degrees.

Recently, a new technique using synthetic aperture radar (SAR) satellite data, called radar interferometry, has been introduced in the analysis of vertical displacement associated with fault movements.

16. Radar backscatter is dominated by the geometrical and electrical properties of surface materials, a fact which must be taken into account during the interpretation of radar images.

And if you're a radar, that's a really bad job.

NATO has adopted a vague term of multilayered protection against incoming threats' in the pursuit of a coherent system that integrates systems from theatre missile defence, mid range missile defence to communications control and sensors.

The new frigates in the future aircraft carrier battle group should play the primary role in anti submarine and short range air defense operations. In the amphibious attack group, they should provide protection to ships. According to these requirements, the new frigates must have strong anti submarine capability and good mid range air defense capability.

At this look angle, radar backscatter is strongly influenced by topographic slope.

It's viral. It seems to spread under the radar very, very quickly.

And he said, Yeah. He said, But that's if you're a radar.

The first of these was a multifrequency, multipolarization radar the most complex civilian radar ever flown in space to study the ecology, water cycles, vegetative cover, as well as oceanography, geology, and volcanology.

The most conventional use of radar data is the recognition of flooded areas by the dark signature of still water in a radar image associated with the all weather capability of the instrument.

The two ERS satellites provide a wealth of radar information for many applications.

18. Radar reflection from vegetation is also influenced by the type of polarization.

(h) Access should be given to training on digital analysis of radar images.

This characteristic makes radar imagery especially useful in differentiating areas of dry from moist soil and in the identification of vegetated zones often characterized by high humidity that would give rise to a strong radar response.

26. Based on the potential usefulness of satellite radar data as presented during the training course, the participants identified a number of projects which could benefit from the radar data collected at the Libreville receiving station.

The satellite uses a radar altimeter to yield precise measurements of sea surface height.

This is a radar speed detector that was developed from a Hot Wheels toy.

In Japan, it rains quite a bit during our rainy season which is from mid June until mid July.

The use of radar images of multiple wavelengths from multiple space platforms (e.g. ERS Radarsat, JERS 1, Shuttle Imaging Radar Seasat) can therefore provide more information and allow for better differentiation in certain land cover and forestry studies.

To track and support the rockets launched, two radar stations are located on Tanegashima Island.
