What is Radar ?
Radar helps you see what’s around you. An antenna mounted high above your boat (often on the mast of a sailing vessel) sends radar waves down towards the ground, hoping to pick up reflections of land or other boats below. It’s not foolproof – it can often pick up images of waves instead of real objects – but it definitely helps you see what’s around you, especially in conditions of poor visibility. A radar set used to be the plaything of the fabulously rich, but now you can get one for around $ 1,000, and a full-on brand name (like Raytheon) for around $ 1,500. It’s worth the money, particulary if you plan to cruise in foggy waters.
RADAR is the UK’s leading pan-disability charity working to represent the need and expectations of over 11 million disabled people in the UK. RADAR plays a key role at the heart of the disability movement, acting with independence to clarify and channel the needs and expectations of disabled people and organisations to Westminster and Whitehall. In support of this, RADAR pioneers upbeat and proactive campaigns to bring about changes in individual attitudes and behaviour. A key ingredient in these is our strategic external alliances and partnerships in support of social inclusion for disabled people. RADAR recognises that, to facilitate disabled people’s full participation in our communities, there is a need to work broadly not narrowly and to explain and engage rather than to hector.
A. Radar stands for Radio Detecting And Ranging. The system operates by transmitting radio waves at certain frequencies which reflect off objects and are picked up by the receiver. When the beam reflects off a moving object, a measurable frequency shift occurs which is then converted into miles per hour to determine the object’s speed. Back to Questions Q.
