along the rising ramp portion of the waveform are many randomly distributed horizontal steps. The presence of these steps increases the interval of time that the jamming signal remains within the IF passband of the receiver. For this reason, they are called dwell-steps. The combination of the dwell-steps and the fast recurring sweep combine to enhance the barrage jamming of the victim receiver. The Guardian-200 system refers to the performance and structure of products that are in use both domestically and internationally. Based on the actual usage, applying advanced computer-aided design technology, optimized structure, increased automation level, simplification of procedures, the system will meet with the user’s frequency requirement. Because of the variety of jamming targets and a wide range of uncertainties, we have adopted the more advanced and effective jamming signal modulation method, which will increase the jamming efficiency in each band, so that to provide security protection and ensure the safety of EOD tasks.
