GOOD reason to feel safe exists, following the turnover this week of the multimillion-peso five coastal surveillance radars by Japan to the Philippines under its Official Security Assistance program.
Defense Secretary Gilberto Teodoro Jr. said the P228-million radars, formally transferred on Wednesday, can be smoothly integrated into the Philippines’ existing military radar systems, underlining the add-ons to these will always be interoperable with the country’s main systems but stopped short of giving details for security reasons.
Interoperable here means the ability of military equipment or groups to operate in conjunction with each other, with the systems, operated by the Philippine Navy, to include radar units, surveillance and monitoring equipment, communications systems, and support components designed to strengthen coastal monitoring and maritime security operations.
Defense officials said integrating the systems will expand surveillance coverage, improve early detection and tracking of surface contacts, and enhance coordination in maritime operations.
The capability will support intelligence, surveillance, and reconnaissance missions, humanitarian assistance and disaster response, and other lawful security operations.
The transfer was finalized during the Nov. 2023 visit of then Japanese Prime Minister Kishida Fumio, when Japan and the Philippines exchanged notes for the provision of the equipment to the Philippine Navy.
What are coastal radar systems to the ordinary Filipino on the street?
These are land-based, shore-mounted sensors designed to monitor, track, and identify vessels, small boats, and low-flying aircraft within coastal waters of this archipelagic country of 7,641 islands whose jagged coastline, ranked fifth longest in the world, stretches about 36,289 kilometers from Batanes to Tawi Tawi.
Operating 24/7 in all weather conditions, the systems use radio waves (S-band to Ku-band) to detect echoes from targets, providing essential, real-time data for maritime security, traffic management, and search-and-rescue operations.
Coastal radar systems function based on the principle of Radio Detection And Ranging (RADAR), with the antenna emiting short, high-frequency electromagnetic waves (microwaves) into the surrounding environment.
When these waves hit an object – such as a ship, buoy, or even a small boat – some of the energy is reflected back toward the radar antenna, then the system receives this returning echo, analyzing the time delay to determine distance and the shift in frequency to calculate speed.
Security experts say advanced signal processing filters out environmental noise (like sea clutter) to display a clear, real-time map of all moving objects.
The systems will be useful for maritime security, traffic management, environment monitoring as well as search and rescue.
The systems can identify illegal vessels, smugglers, or unauthorized entry into territorial waters of the Philippines, monitor shipping lanes to prevent collisions in busy, narrow, or congested waters, detect oil spills or track maritime activity to protect natural resources as well as locate vessels in distress.
We hear the ordinary Filipino join the establishment in expressing deep appreciation for the support and the transfer of this essential materiel, which significantly enhances the country’s capacity building.
