Abstract
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.
