Coastal surveillance: Sri Lanka
Sri Lanka is an island astride some of the world's busiest sea lanes, so the approaches all around it matter as much as the coast itself. Coastal radar sees only so far around an island shore, and the gaps between stations, around headlands, harbours and the narrow channels off the coast, are exploited daily.
An island where the approaches are the front line
Because shipping funnels past Sri Lanka in every direction, the island's security picture is defined by its approaches: dense commercial traffic offshore, fishing fleets close inshore, and narrow channels where honest and suspect movement mix. A chain of coastal radar covers the arcs it can see, but the curvature of the earth and the spacing of stations leave low, slow and small contacts unresolved, and a hull running dark is hardest to distinguish exactly where traffic is thickest. The need is a continuous, fused picture from the beach out to the edge of the exclusive economic zone all around the island.
A layered picture around the whole coast
Passive radar extends coverage across the seams without adding an emitter a hostile party can locate or jam, filling the inshore gaps active stations leave around a circular coast. Vessel detection from orbit builds the wide-area offshore layer astride the sea lanes, flagging contacts behaving unlike honest transit, while observation drones classify the contacts that matter around ports and anchorages. Because these capabilities come from independent, non-aligned makers, the maritime picture is tasked on national priorities and retained under national control rather than gated by a foreign feed.
How engagement works in Sri Lanka
Unstrat engages Sri Lanka as an independent, non-aligned prime vendor: one accountable team representing the manufacturers directly, with end-use certified equipment and in-region sustainment rather than a distribution arrangement. A programme typically begins on the busiest approaches and extends into a common picture the navy and coastguard operate themselves, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
A fused picture where the approaches are the front line
Because busy sea lanes funnel traffic past the island in every direction, an engagement opens with a briefing for the navy and coastguard on how a picture would hold all around the coast, not just along it. The sensing involved is controlled capability, so export-control clearance and end-use confirmation are settled before any representation. The layers are then matched to Sri Lanka's real conditions: passive radar filling the inshore gaps of a circular coast, orbital vessel detection astride the lanes to pick a dark hull from thick transit traffic, observation drones around ports and anchorages. A programme is phased, instrumenting the busiest approaches first with in-region sustainment behind them, and broadening into a common picture the operators run themselves. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals, so the awareness that protects the approaches stays tasked on Sri Lankan priorities.

Adjacent priorities in Sri Lanka
Illegal, unreported and unregulated fishing drains Sri Lanka's coastal economy and undermines sovereignty over an exclusive economic zone that reaches out into busy waters. Foreign trawlers work the edges of the zone where patrol vessels rarely reach, run dark to avoid cooperative tracking, and leave the island's own fleet with dwindling stocks.
Problem pagePiracy raises insurance costs, deters shipping and endangers seafarers. Space-based vessel monitoring, aerial patrol and hardened port and vessel systems let coastal states detect threats early and protect the shipping lanes their economies depend on.
Problem pageSri Lanka's ports sit astride major shipping routes, handling transhipment and national trade in a small, exposed footprint that is vulnerable from the water, the air and the network at once. A gateway this busy and this strategically placed is a first-order target where a stoppage carries consequences well beyond the harbour wall.

Sri Lanka: security context
Sri Lanka's island position shapes its priorities: maritime domain awareness astride busy sea lanes, protection of its exclusive economic zone and fisheries, coastal surveillance, and security of critical infrastructure. It is an environment where the approaches around the island matter as much as the coast itself.
An accountable single-channel engagement gives Sri Lanka a coherent counterpart for those priorities, maritime domain awareness, EEZ and fisheries protection, coastal surveillance and infrastructure protection. A security agency gains end-use certified equipment, disciplined export-control handling and localisation arrangements scoped per programme rather than promised in advance.
About this challenge
Coastal radar sees only so far, and gaps between stations are exploited daily. Passive radar that adds coverage without emitting, satellite vessel detection and satellite-data fisheries analytics extend the maritime picture from the beach to the edge of the EEZ.
Frequently asked questions
Why do the approaches matter so much for an island like Sri Lanka?
Because busy sea lanes funnel traffic past the island in every direction, the approaches all around it are effectively the front line. A layered picture (passive radar inshore, orbital vessel detection offshore and observation drones around ports) extends awareness from the beach to the edge of the exclusive economic zone. We would welcome the chance to brief your team.
Why is passive radar useful around an island coast?
Passive radar detects contacts by exploiting ambient signals, so it emits nothing a hostile party can locate or jam, and it fills the inshore gaps a circular coast leaves between fixed stations, adding coverage without adding a signature.
Does the maritime picture stay under national control?
Yes. The sensing capabilities come from independent, non-aligned makers, so the picture is tasked on Sri Lankan priorities and retained nationally, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
