Ioannis - please clarify. If you are referring to a specific example, then include (for example) the link to it and describe what you are observing and what you expect to observe.

I have a set of coherent high range resolution profile (HRRP) of a flat plate stored in a matrix. The matrix has size 3601 (azimuth is 0:0.1:360 degress) by 4600, which is the number of range bins. The HRRP matrix is centred around the centre of rotation of the flat plate. The HRRP matrix contains complex numbers (amplitude and phase). I execute the following: Image_Plate = iradon(HRRP, azimuth);

The above command does not work. Instead if I execute Image_Plate = iradon(abs(HRRP),azimuth) it works, but I don't get an exact image of the flat plate. Note that HRRP are also called sinograms.
