THE RF ENVIRONMENT EMULATION FOR FREQUENCY HOPPING RADAR AND ITS CRITICAL TECHNOLOGY

The signal character of frequency hopping radar seeker and the basic method for emulating the RF environment of frequency hopping radar are described. The instantaneous frequency measurement (IFM) emulating schemes, RF delay line emulating schemes and their critical technologies are emphatically discussed. To improve frequency precision by improving frequency correcting method is critical technology of IFM emulating schemes. To exploit good performance RF delay line with low loss and wide frequency band is critical technology of RF delay line emulating schemes. The advantage and disadvantage of two emulating schemes are also compared in this paper.
