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

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)

What is the phase difference between the e and i waveforms? (write your answer in degrees to two decimal points)

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 .

For the following display, the vertical sensistivity is 2V/div and the horizontal sensitivity is 9msec/div, what is the phase of this waveform? (write your answer in degrees to 2 decimal points)

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
