Chapter 1 Synthetic Aperture Radars (SAR) Imaging Basics The word “radar” is an acronym for Radio Detection and Ranging.A radar measures the distance, or range, to an object by transmitting an electromagnetic signal to and receiving an echo reflected from the object.Since electromagnetic Spaceborne Synthetic Aperture Radar (SAR) imagery maps the surface microwave radar reflectivity at resolutions from a sub-meter to 100 m depending on the particular SAR satellite and mode. SEASAT (L-band, HH) SAR image of the ocean south and east of Nantucket Island collected on27 August 1978 (Rev 880, 1234 GMT). It features enhanced capability in terms of coverage, range of incidence angles, polarisation, and modes of operation. Considering a wide usage of millimeter wave radar for automobile, security and surveillance, we are proposing a new imaging technique [3,4] combining synthetic aperture radar (SAR) and millimeter wave radar. Since a radar provides its own illumination, imagery is independent of the time of day. is usually performed by airborne radar to interrogate the terrain [2], and is not suitable for civilian usage. Besides these relative low resolution measurements, microwave spaceborne Synthetic Aperture Radar (SAR) sensors can also provide valuable high resolution spatial observations and thus map flood extent (Henry et al., 2006, Oberstadler et al., 1997).

It provides higher performance than theJERS-1's synthetic aperture radar … 55, … The Phased Array type L-band Synthetic Aperture Radar (PALSAR) is an active microwave sensor using L-band frequency to achieve cloud-free and day-and-night land observation.
