ACR 430

The ACR430 (Abbr. of Airfield Control Radar) was an X-Band airfield control radar. It was designed between the 1950s and the mid 1960s as a replacement for the older Type 424 radar to meet the requirements of air surveillance control. The ACR430 radar employs a two-beam aerial system (high Fan-beam und low Pencil-beam), two transmitters and receivers and two operational displays. It used fixed circular polarisation to reduce the effects of rain clutter.
