The R&S®Pulse Sequencer software offers an easy way to simulate moving radar emitters and a moving receiver for EW receiver tests. The software together with the R&S®SMW200A vector signal generator is a powerful radar simulator. It enables engineers to generate highly dynamic 3D scenarios in the lab.

From slowly moving vessels to rapidly maneuvering airplanes, simulating moving radar emitters is relevant for many test cases. RF level variation at the antenna input of EW receivers due to approaching or departing emitters follows the 1/R2 law. Often the pointing direction of the main lobe of installed antennas changes because of a dynamic change of the emitter or receiver platform attitude. This leads to additional level variations. 

Testing EW receivers under realistic scenarios is therefore crucial to their reliable performance in the field. However, it is costly and time-consuming to test receivers in their real operational environment. In addition, it could be too late to make major changes to the system if things do not work out as expected. This is why engineers need an easier and faster method to assess the receiver‘s performance.
