Abstract

PURPOSE:To remove video oscillation due to a wave and to recognize an image of a school of fish clearly by limiting the output of an oscillation sensor, and making only an echo signal arriving from a slanting surface of a target into an image selectively. CONSTITUTION:The oscillation sensor 8 is installed to a location where it receives nearly the same oscillation condition with a transducer 1 to detect the extent of oscillation. The extent of oscillation is applied to a transmission and reception control circuit 7 and when the extent exceeds a predetermined value, control is carried out so that an echo signal applied from a receiving circuit to a main storage circuit 10 is canceled, or that the storage contents of the circuit 10 are not updated. Consequently, only echo signals less than specified oscillation are stored in the circuit 10 and applied to a modulating circuit 11. Thus, the output of the sensor 8 is limited to make only echo signals arriving from slanting surfaces of the target in the water into an image selectively, so an image 19 of a body such as a school of fish is recognized clearly.

In the vibration removal sonar device according to claim 1, an echo signal obtained by scanning a receiving beam is stored in a location corresponding to a predetermined sector of the main memory circuit, and the echo signal is stored in a location corresponding to a predetermined sector of the main memory circuit. It is characterized in that the address circuit of the Lu Ji memory and the address circuit of the display operate so that the deflection and density modulation of the electron beam of the cathode ray tube are performed so as to display the phasic position of the object that produced the moon. Vibration removal nonar device. 3. In the vibration removal sonar device according to claim 1, when the output of the vibration sensor is within a predetermined range,
What is claimed is: 1. An agitation removal nonar device characterized in that it operates both a transmitting circuit and a receiving circuit or only the receiving circuit. 4 Special, v! I- In the vibration removal nonar device as set forth in claim 1, the modulation circuit of the cathode ray tube is divided according to the intensity of the echo signal, and the three primary color electric beams of the color cathode ray tube are density-modulated, thereby converting the echo image into color. An agitation removal nonar device characterized by displaying. 5. In the agitation removal sonar device according to claim 1, the agitation sensor is connected to a rotating shaft and rotates.
An agitation elimination sonar device characterized in that one or both of a transmission/reception control circuit and a main memory circuit are controlled by the agitation mouse in the direction of the sector to which the transuser is directed.
