The carriers Liaoning and Type 001A rely on airborne early warning helicopters and an integrated radar system to detect enemies. But these systems with their weaker warning capability risk exposing the carrier's position, the report said. Phased radar carried by an airborne early warning helicopter is limited in size. The early warning distance, time and accuracy is thus limited. An aircraft like the KJ-600 has a larger radar, flies higher than a helicopter and sees farther and more clearly.
