An embodiment of the present invention is a method of transmitting a multibeam jamming signal of an array antenna and including: a signal receiving operation of receiving a radar signal from a plurality of radars; a signal analysis operation of analyzing the received radar signal and identifying an angle and frequency of the signal; a control phase value calculating operation of calculating a control phase value of each array path of the array antenna for each of the identified angles; and a multibeam jamming signal transmission operation of calculating a multibeam jamming signal based on the calculated control phase value and transmitting the multibeam jamming signal for each identified frequency.

Method for transmitting multibeam steering jamming signal, and transmitting system for implementing method

System and method for removing channel phase error in a phase comparison direction finder. By using this system, the phase error, generated in the channel path in finding the direction by using the phase comparison direction finder, can be injected into the receiving channel and removed by using the frequency and intensity of the signal stored in the PDW table. Furthermore, the direction finding correction look-up table can be made using only radiation correction of the antenna unit of the direction finder and channel correction can be carried out without calibrating the direction finder for the direction finding correction look-up table when devices are replaced in the channel of receiving path of the direction finder.
