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

Provided are an apparatus and a method for measuring a frequency of a broadband signal by using low-speed ADCs having sub-Nyquist sampling rates. A plurality of channels each including a low-speed ADC having a sub-Nyquist sampling rate (e.g. sampling frequency from several MHz to hundreds of MHz) are provided, and the frequency of an input signal corresponding to a combination of frequencies calculated through the respective channels is estimated. Therefore, as the number of channels increases, the range of measurable frequencies may be extended.
