LDAR
Lightning Detection and Ranging

The Lightning Detection and Ranging (LDAR) system is a ground-based lightning network located at the Kennedy Space Center (KSC). It consists of seven very high-frequency (VHF) radio receivers that detect radio pulses produced by lightning. These seven receivers are arranged in a hexagonal pattern about 6 to 10 km apart from the central receiver. The LDAR system operates at the 66 MHz frequency and has a bandwidth of 6 MHz. It has a typical detection range of 100 km and a time resolution of 10 ns. It provides near real-time mapping of lightning in support of Space Shuttle operations.
