Les techniques de télédétection hyperfréquence passive sont basées sur les mesures du rayonnement hyperfréquence émis naturellement par la surface terrestre. Le rayonnement émis est détecté par un radiomètre hyperfréquence et la quantité de rayonnement est exprimée en général comme une température équivalente hyperfréquence (TB) en Kelvin (K). L'avantage principal de l'utilisation de la télédétection hyperfréquence pour l'observation de la Terre réside dans la capacité de l'énergie hyperfréquence à traverser les nuages et certaines formes de précipitations, et contrairement aux techniques de détection visible, elle n'est pas dépendante du soleil comme source d'illumination.  8, record 1, French, - t%C3%A9l%C3%A9d%C3%A9tection%20en%20hyperfr%C3%A9quences%20passives

Passive remote sensing makes use of sensors that detect the reflected or emitted electro-magnetic radiation from natural sources.

... imaging radar systems are active sensors that "illuminate" surface features with broadcast microwave energy and record a returned signal. Most imaging radar systems produce microwaves with wavelengths between 1 cm and 1 meter, longer than the wavelengths used in weather radar to detect rain and snow. These longer wavelength microwave signals propagate through the atmosphere and clouds with almost no interaction or weakening. As a result imaging radar systems can be used to map surface features day or night and in almost any weather conditions. These characteristics make radar imaging especially useful in tropical and polar regions where persistent cloud cover hampers optical remote sensing efforts.  2, record 3, English, - surface%20feature

The recent emergence of airborne P-band interferometric synthetic aperture radar(IFSAR), a high-resolution, microwave remote sensing technology, has the potential to provide significantly more accurate terrain models in forested areas. Low-frequency, P-band radar energy physically penetrates through the vegetation canopy and reflects from the underlying terrain surface, allowing for accurate measurement of the terrain surface elevation even in areas with dense forest cover.  3, record 7, English, - interferometric%20synthetic%20aperture%20radar
