Sperry Marine, a business unit of Northrop Grumman Corporation, today announced that its Decca BridgeMaster E 340 is the first flat-screen radar to be type approved to meet the international carriage requirements for automatic radar plotting aids (ARPA). The flat-screen radars provide significant savings in space and weight over traditional CRT displays. This is especially important for high-speed craft, in which size and weight are significant constraints. The flat-screen BridgeMaster E 340 display has a full 340-cm radar circle as required for ARPA type approval. The active-matrix high-resolution LCD provides wide viewing angles and a bright, clear picture in direct sunshine. The screen may be dimmed to avoid glare for nighttime operation.
