This application relates to a noise signal generating apparatus. In one aspect, the apparatus includes a bandwidth expansion unit configured to generate a noise signal having a second bandwidth by expanding a noise source signal having a first bandwidth to the second bandwidth that is greater than the first bandwidth. The apparatus may also include a randomization unit configured to perform randomization and output the generated noise signal having the second bandwidth.

Method and apparatus for generating noise signal

An apparatus for generating a jamming signal comprises a signal receiving unit configured to receive an external pulse signal, an amplitude signal generating unit configured to generate an amplified signal by amplifying the pulse signal, a noise signal generating unit configured to generate a noise signal having a bandwidth including a bandwidth of the pulse signal, a control unit configured to control the amplified signal generating unit and the noise signal generating unit such that a signal-to-noise ratio of the amplified signal and the noise signal to be received by an apparatus that has transmitted the pulse signal becomes constant based on characteristics of the pulse signal and a signal radiating unit configured to radiate the amplified signal and the noise signal.

Apparatus and method for generating jamming signal

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.
