The TIRA system consists of a narrow band tracking radar and a high resolution imaging radar.

For objects smaller than the radar wavelength, RCS is inversely proportional to the 4th power of the wavelength (or to the 4th power of the frequency).

(c) Radar cross section the returned signature of an orbiting object, from which shape, orientation and size can be derived (the radar cross section is dependent on the wavelength of the radar therefore, the wavelength of the measurement must also be recorded)

Once the data are collected, the radar might return to the beam park mode.

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

By contrast, radar satellites, such as the ERS 1 and 2, JERS and Radarsat, exploited the microwave region of the spectrum.

Measurements of small radar calibration satellites revealed that the L band radar can now observe space debris of 1.7 cm size in the 800 km range.

Radar penetration of vegetation forests and agricultural crops is influenced by the wavelength of the signal.

. ERS 1 also carried a radar altimeter that operated at a wavelength of 2 cm.

ERS 1 also carries a radar altimeter (RA) that operates at a wavelength of 2 cm.

Here's that Los Angeles picture, sir. This is a sonic radar picture.

In the tracking mode the radar follows an object for a few minutes, gaining data on angular direction, range, range rate, amplitude and phase of the radar echoes.

The payloads of the satellite segment of both systems would be designed to monitor the land and ocean environment, the geosphere, hydrosphere and meteorological conditions, with the aid of visible, near infrared, microwave, short wave and thermal radiometers, synthetic aperture radar, radar altimeter and scattering lidar.

Fred, Polly's dead.

In the short term, the remote sensing programme will be supplemented with observations in the microwave range by means of radar.

While ERS and Radarsat satellites operate in the C band, JERS 1 operates in the longer L band.

Methods and algorithms have been developed to analyse narrow band radar signatures, to compute radar images from high resolution radar data, and to estimate physical properties of space debris like size, shape, dimensions, intrinsic motion, mass, orbit and orbital lifetime.

. Canada apos s Radarsat had been launched on 4 November 1995 carrying a SAR instrument on board that would operate in C band with multi mode single polarization.

A cooperative programme with the German Space Agency (DARA) and NASA to develop an X band synthetic aperture radar, X SAR was flown (April and September 1994) on board the space shuttle with the Spaceborne Imaging Radar C (SIR C) as part of the Space Radar Laboratory (SRL) for multispectral radar observations.

Both satellites are equipped with microwave (radar) instrumentation which penetrates cloud cover and darkness and provides information 24 hours a day.

In wave mode, SAR is used to measure ocean wave spectra and wave direction, while in scatterometer mode, AMI is used to measure wind direction and speed at the ocean surface.

Interaction of microwave energy with materials depends not only on its frequency but also on the polarization of the radar beam.

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