Coastal surveillance radar made in Indonesia that assists surveillance and safety on the Coastal Coast, equipped with reliable Low Probability of Intercept (LPI) technology against the threat of Radar Detectors and Jammers.
Braja CX-4M is the 4th generation coastal surveillance radar produced by PT. Dua Empat Tujuh. This radar uses a solid state frequency modulated continuous wave (FMCW) system with very low transmit power and frequency hopping. This capability allows the radar to carry out surveillance with signals that are difficult for opponents to detect. This radar also implements the latest hardware and uses advanced signal processing techniques so that it has superior target detection capabilities. Several Braja CX-4M Radars can be integrated into the radar network using the IRNET (Indonesia Radar NETwork) system.
What Make Us Different
FMCW
Advanced radar technology, Frequency Modulated Continuous Wave
