Best possible resolution that can be achieved by SAR is when length of antenna = X * Azimuth Resolution. What is the value of X? 1/2 1/4 2.0 4.0

Calculate range resolution of a synthetic aperture radar, if the pulse width is 3μsec. (Assume c = 3 x 108 m/s) 450m 900m 300m 600m

A radar signal contains amplitude and phase information. is the strength of the radar response and is the fraction of one complete sine wave cycle (a single SAR wavelength). The phase of the SAR image is determined primarily by the distance between the satellite antenna and the ground targets.A satellite SAR can observe the same area from slightly different look angles. This can be done either simultaneously (with two radars mounted on the same platform) or at different times by exploiting repeated of the same satellite. The distance between the two satellites (or orbits) is called .

If a SAR image pixel has a value b+ai, its phase ɸ is given by _______ sin-1(a/b) sin-1(b/a) tan-1(b/a) tan-1(a/b)

A pixel in a SAR image looks like 9+5i. Calculate its phase ɸ (in degrees). 60.95 - 60.98 28.90 - 29.10 28.10 - 28.30 60.93 - 60.95
