ABSTRACT
Synthetic Aperture Radar or SAR is an imaging radar system
that sends a microwave pulse to the surface of the earth and register
the reflections from the earth's surface . On -board processing and
compression of data obtained from the SAR is vital for image formation
.The development of enabling technologies for space-borne SAR
instruments have been a major focus of research and development during
the last few years . At present the SAR systems provides only images
and in future it will have t ....etc

Abstract
Destructive and non-destructive methods have been used for the determination of micro-traces of antimony in high-purity silicon powder. The destructive method was based on sub-stoichiometric radio-activation analysis with solvent extraction using BPHA and cupferron as organic reagents. The antimony contents in high-purity silicon can be determined by the proposed method.
A new non-destructive method was developed for the detection of refrigerant leakage at an evaporator's inflow. Nitrogen and oxygen gas were suc ....etc

RADAR AND SYNTHETIC APERTURE RADAR BASICS
PRINCIPLES OF RADAR
HOW DOES RADAR WORK?
• RADAR = Radio Detection And Ranging
• Since radar pulses propagate at the speed of light, the difference to the “target” is proportional to the time it takes between the transmit event and reception of the radar echo

1. INTRODUCTION

Silicon has been the heart of the world's technology boom for nearly half a century, but microprocessor manufacturers have all but squeezed the life out of it. The current technology used to make microprocessors will begin to reach its limit around 2006. At that time, chipmakers will have to look to other technologies to cram more transistors onto silicon to create more powerful chips. Many are already looking at extreme-ultraviolet lithography (EUVL) as a way to extend the life of silicon at least un ....etc

Abstract
A pressure sensor that combines two principles ofmeasurement into one integrated unit with optical and electronicparts is fabricated and tested. The sensing element for both integratedparts is an embossed silicon diaphragm that deflects underdifferential pressure. The optical part of the sensor is based onFabry–Perot interferometry; the electronic part of the sensor isbased on the piezoresistive effect in silicon. In the application ofFabry–Perot interferometry, the sensing element utilizes an opticalcavity, where interfer ....etc

In an effort to provide more detailed information about epileptic lesions in neural tissuefor the purpose of efficient removal, an Optical Coherence Tomography system was built to provide non-destructive imaging. The device is based upon the principle of a low-coherenceinterferometer. Such an instrument can detect if a particular point within a sample of tissue reflects light; an integration and interpretation of many scans of many points provides a highresolution image. The device built for this investigation has been successful in scanning se ....etc

1. INTRODUCTION
Deep space exploration and utilization are all along the dreams of human beings. The exploration and utilization of the deep space are all along the dreams of human beings. Since the Soviet Union began to explore the moon by using moon-1 in January 1959, there has existed drastic competition in the area of deep space exploration and utilization among the countries all over the world, especially among the United State, Russia and some countries in Europe. Besides the technologies of launching and controllin ....etc

Optical Coherence Tomography (OCT) is an imaging technique that is similar in principle to ultrasound, but with superior resolution. It relies on exposing a sample to a burst of light and then measuring the reflective response from different depths and is therefore capable of scanning non-invasively beneath the surface of the sample. In ultrasound imaging, it is relatively easy to measure the time delay of each reflected packet. However, for light pulses, interferometry must be used to measure the displacement with meaningful accuracy. The amou ....etc
