  In this report, we discuss possibilities to detect a signal at the target
from the quantum illumination protocol, that could serve as a quantum radar. We
assume a simple universal detecting schema on the target and study if it is
possible to discover the quantum illumination measurement and in what
conditions considering the microwave regime. Assuming many simplifications, we
found that the possibility or the advantage of the detection of the quantum
illumination measurement strongly depends on the realization of the quantum
illumination protocol.
