It is not possible to construct an ideal filter.

In order to enhance the detail in your image you should use a high pass filter.

Using entropic coding it is possible to represent a symbol with less number of bits than the entropy (on average).

Is the following property true (X - Fourier transform)?

Signals are often transformed to frequency domain to perform speed up filtering (using Convolution theorem).

Not all active SAR systems are side-looking.

In order to perform a FFT on a signal it is required to pad the signal so that the number of elements in it is of power of 2.

What is the inverse Fourier transform of:

Parseval's identity is analogous to Pythagorean theorem.

Run-length coding is an efficient method to compress black and white images.
