AMBER 1800

The AMBER 1800 is a self-propelled, mobile, long-range VHF air surveillance 2D radar. Operating within a frequency range of 140 MHz to 180 MHz, the system utilizes a horizontally linearly polarized antenna composed of two rows, each containing 12 circular modules. For short-range detection, it employs a 6-microsecond keyed on/off waveform, while long-range detection uses phase-coded pulse compression, specifically a 13-element Barker code resulting in a 78-microsecond pulse, with optional nested codes up to 51 x 6 microseconds. The radar has an instrumented range of 360 km, optionally 500 km, and was first showcased by Lithuania's LitakTak company at the MSPO 2014 exhibition in Kielce, Poland, in September 2014.
