Braja CX-4M

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

Solid State Transceiver
Using Commercial of The Shelf Solid State Technology, ensures long component life
Low Power Transmit

1000 times lower transmit power than pulse radar

Frequency Hopping

Agility frequency technology with several different patterns

Low Probability of Intercept
Has a low probability of intercept making it difficult for the radar detector to detect the transmit signal
Build In Test
Monitor system performance so that it can easily detect system failures
Advance Signal Processing
Advanced signal processing makes it easy to detect targets in Low SNR environments and lots of clutter
