Record number: 10, Textual support number: 1 CONT
Pulse Compression. In collecting the SAR data, a long-duration linear FM [frequency modulation] pulse is transmitted. This allows the pulse energy to be transmitted with a lower peak power. The linear FM pulse has the property that, when filtered with a matched filter, the result is a narrow pulse in which all the pulse energy has been collected to the peak value. Thus, when a matched filter is applied to the received echo, it is as if a narrow pulse were transmitted, with its corresponding range resolution and signal-to-noise ratio. 3, record 10, English, - pulse%20compression

Traitement en distance [-] compression d'impulsion. Pour obtenir une résolution en distance satisfaisante (de l'ordre de quelques mètres) il est nécessaire que l'impulsion ait une durée d'émission très brève (quelques nano-secondes). Or, une telle durée conduirait à émettre une impulsion de puissance très élevée afin d'obtenir en retour un signal suffisant compte tenu des amortissements lors du trajet, du coefficient de rétrodiffusion des cibles, et des traitements au niveau de l'antenne [...]. Les valeurs d'énergie nécessaires sont difficilement compatibles avec les instruments satellitaires disponibles. La finesse de résolution est donc obtenue en utilisant une technique dite de modulation de fréquence. Un signal de durée d'émission importante (quelques micro-secondes) est utilisé, permettant ainsi d'augmenter l'énergie transmise; ce signal est modulé linéairement en fréquence afin d'occuper une plus grande largeur de bande. 2, record 10, French, - compression%20d%27impulsion

Record number: 11, Textual support number: 1 CONT
The Gamma filter performs gamma map filtering. Gamma filtering is primarily used on radar data to remove high frequency noise(speckle) while preserving high frequency features(edges). The Gamma Map filter was first proposed by Kuan.... Lopes modified the Kuan Map filter by assuming a gamma distributed scene and setting up two thresholds. The gamma filter size ranges from 1 to 11. Different filter sizes will greatly affect the quality of processed images. If the filter is too small, the noise filtering algorithm is not effective. If the filter is too large, subtle details of the image will be lost in the filtering process. A 7x7 filter usually gives the best results.... The GAMMA filter performs spatial filtering on each individual pixel in an image using the grey level values in a square window surrounding each pixel. The dimensions of the filter must be odd, and can be from 3x3 to 11x11 pixels. 2, record 11, English, - gamma%20filter

In this type of application the crystal is used to produce very stable oscillations at a precise frequency or as a highly selective bandpass filter.

Determination of the effective opening size, dw, FIH. The effective opening size of a geotextile, dw, is determined by wet sieving quartz sand of known composition using modified sieving equipment. The geotextile functions as a sieve.... The test sample,(diameter 18 cm), is clamped into a sieve frame. The sand, which has a dry weight of 100 g for wovens and a dry weight of 300 g for non-wovens, is then sprinkled onto the sample. The sand is then sprayed continuously with water and sieved for 15 minutes in a modified sieve machine with a vertical amplitude of 3 mm at a frequency of 50 Hz. The sand which passes through the geotextile sample is caught on a paper filter and then analyzed with [different sieves].... The effective opening size, dw, is found from the coarsest sand fraction which has passed through the test sample and in which there is still a defined quantity in relation to the original fraction. 4, record 23, English, - effective%20opening%20size
