摘要： PURPOSE:To assist nighttime navigation effectively by a method wherein a target signal from a radar is converted into a target signal in a coordinate system taken by a snooperscope camera and the converted target signal is superposed on an image signal from the snooperscope camera and displayed in a display unit. CONSTITUTION:In a distance and bearing conversion device 10, the distance and the bearing contained in a target signal of each target are subjected to coordinate conversion into a target signal in a coordinate system taken by a snooperscope camera 4 so that each target taken by a radar 1 can be displayed on a display unit 7b together with each target taken by the camera 4. A radar image processing device 12 receives herein a conversion index signal of each target from the device 10, a moving/standstill discrimination signal of each target from a moving target/standing-still target discriminating device 8, a target size signal of each target from a reception signal expansion detecting device 9 and an alarm signal from a collision prevention alarm device 11, and outputs a target pseudo image signal.

摘要： PURPOSE:To detect and threaten whales, marine organism and sea floating matter by installing an indicating means which receives the outputs of the first transmitter-receiver and the second transmitter-receiver, detects whales or sea floating matter in front of a high-speed ship and displays a distance thereto and the direction thereof. CONSTITUTION:The first transmitter-receiver 33 is directed in the positive bow direction, the second transmitter-receiver 34 is directed in the direction inclined to the right side by a prescribed angle from the positive bow direction, and ultrasonic waves with different frequencies are transmitted from the first transmitter-receiver 33 and the second transmitter-receiver 34. By detecting the right/left position (position of the right or left to the center line of a hull) of a sea floating matter or a whale, it is possible to perform proper navigation. When transmitting the ultrasonic waves temporarily continuously from the first and second transmitter-receivers 33, 34, threatening effect is sometimes reduced by the paralysis of a whale's acoustic sense, however, it is possible to enhance threatening effect because of the intermittent transmission of ultrasonic waves.
