Why is it important?
Ideally, the OoB emission of the PLFM radar far from the dominant frequency will decay and be lower than the level of spurious emission. Especially in the field of civil communication which is extremely short of channel resources, the level of OoB emission tends to be severely restricted. However, due to their wide operating frequency band and their demand for a further detection range of the phased array radar, it is often difficult to withstand the dominant frequency insertion loss caused by the suppression of OoB emission .
