    • A sector scanning sonar can direct a transmitter/receiver (1) in a desired direction by turning means (2, 4, 201) and angle-of-depression setting means (3, 4, 301). Since the elements of the transmitter/receiver (1) are circularly arranged, it has been impossible to display the detected information in all circumferential directions with a sufficient intensity on a cathode ray display circuit. To eliminate this drawback, the detected information from all the circumferential directions concerning to the selected sector, distance, and azimuth is written in a main memory circuit (10), is controlled by an address control circuit (8), is stored temporarily, is controlled to correspond to the scanning format of raster scan type color display means (11, 13, 14) by an address control means (12), is repeatedly read, and is applied to the display means (11, 13, 14).
    • 扇形扫描声纳可以通过转动装置(2,4,1201)和倾角设定装置(3,4,1301)将发射器/接收器(1)沿所需方向引导。 由于发送器/接收器(1)的元件是圆形布置的,所以不可能在阴极射线显示电路上以足够的强度在所有圆周方向上显示检测到的信息。 为了消除这个缺点,来自与所选扇区,距离和方位角有关的所有圆周方向的检测信息被写入主存储器电路(10),由地址控制电路(8)控制,暂时存储,是 通过地址控制装置(12)被控制为对应于光栅扫描型彩色显示装置(11,13,14)的扫描格式,被重复读取,并且被施加到显示装置(11,13,14)。
