Navigation and target detection at night or in poor visibility is always a problem, but, over the millennia, bats developed a natural solu- tion. Bats have a built-in "radar" that is im- mensely efficient and enormously sophisti- cated. In flight, for example, some species can easily detect and avoid very fine suspended wires. Bats are able to accurately determine range and bearing, even discriminate between two closely spaced objects. In addition, bats can readily measure the relative velocity be- tween themselves and a target by consecutive range measurements or by doppler frequency shift. The most amazing ability, however, is that bats not only can determine target size, but also shape and surface properties.

Furuno has a product line that solves navi- gation and target detection problems for com- mercial vessel operators: Our newest family of 12- and 16-inch radars. These systems are available in 25 kW X-band and 60 kW S- band versions, interswitched if desired, and offer dual VRM's, offcentering, "echo stretch," a variety of antenna lengths, and ten range scales to 120 miles plus a 12-mile true motion scale. All units meet current IMO requirements for ocean-going vessels and pro- vide features such as digital signal processing, continuously visible EBL, Furuno's exclusive hybrid microwave IC receiver circuitry for high sensitivity, and a log amplifier for better target detection at all ranges in any weather.

For complete information on the whole range of 12- and 16-inch radars, and their many options, contact Furuno today. (1 FURUNO
