Direction Finding System

A clean radio environment is created through the direction finding of jamming, interference and illegal radio
waves with the establishment of the high-performance direction finding system with great efficiency
developed by our own technology.

System Configuration

• · Frequency Range : 30MHz ~ 3GHz
• · Number of Times of Direction Finding : 50 times (MUSIC)
• · Accuracy of Direction Finding: 1.2 degrees ~ 1.7 degrees (rms)
• · Receiver Sensitivity : -107dBm o Functions
  • - Direction finding to detect illegal signal sources
  • - Operated in conjunction with the intelligent radio monitoring system, fixed direction finding system in
       the Capital area and mobile direction finding system
  • - Operated in conjunction with the maritime and aviation system, and command and control system
