Abstract :

With the end of World War II and the rapid advent of war technology, wars have shifted to electronic warfare, and today a nation can win wars that are more powerful in the field of telecommunications and electronic warfare. The purpose of this article is to promote new content in the field of electronic warfare and we try to introduce and introduce new techniques of electronic attacks on victim radar systems. With the exception of false targets created by point or sweep jams, most false targets are created with automatic responders or repeaters. An automatic response generator for producing false targets includes a receiver, a variable delay circuit, a signal generator, a power amplifier, and an antenna. Upon receiving a pulse from the threatening radar, the transponder waits for the time corresponding to the target man's distance to the false target, and then sends a similar echo signal to the radar. . As soon as the pulse is received from the threatening radar, the transponder delays it sufficiently to cause the difference in distance to create a false target. Then, a pulse similar to the RF echo pulse of the radar is returned to it.
