    Calculating PFA and PD of a radar system based on SNR

    Hi everyone, Normally when calculating the probability of false alarm (PFA) and probability of (PD) of a radar system for a known SNR I use tables in literature, as existing of course for all types of targets. But currently, I try to figure out how to calculate them by myself. I assume the only...

    Cross-pol component in offset reflector geometry

    Hi all, I would like to understand in more detail the physical reason, why an offset in a reflector antenna leads to an increased cross-pol component. I look at linear polarized antennas. For sure the asymmetric illumination of the reflector is the cause for the cross-pol component. My question...

    Rule of thumb for beam tilting for a reflector antenna with off-focus feed

    Hi, I'm looking for a rule of thumb for the beam tilting of a reflector antenna when the feed has an offset relative to the focus. So basically something like focal length+feed offset equals x° of beam tilting. I'm assume that the exact tilting depends on illumination etc., but for the first...
