Method utilizing orthogonal array to form unmanned ship monitoring area supersonic wave three-dimensional image

Abstract

The invention provides a method utilizing an orthogonal array to form an unmanned ship monitoring area supersonic wave three-dimensional image. A routine mode is about utilizing a two-dimensional image mode to operate a device to acquire a two-dimensional image, a transmitting linearity phased array is only used for realizing wave beam formation of a fixed inclination angle phi of 0 degree, a reception linearity phased array is only used for realizing focusing operation of reception waves of the fixed inclination angle phi of 0 degree, a transmitter enables motions of the transmitting linearity phased array, so one transmitting wave plane can be formed each time at the position of the inclination angle of 0 degree, a supersonic wave echo signal received by the reception linearity phased array is processed in a receiver, a parallel light beam formation device corresponds to one azimuth and focuses the azimuth to a signal scanning line, focused signals are processed through an image signal processor and are then displayed on a display device, operations are repeated, and a three-dimensional image plane same as a plane formed through a two-dimensional image formation flow is formed.

Description

technical field [0001] The invention relates to an imaging method for an unmanned ship monitoring area, in particular, it is formed by using an ultrasonic orthogonal array. Background technique [0002] Drones and self-driving cars have dominated the tech world, but the low-key unmanned ships are less well-known. In novels, unmanned ships are always shrouded in a sense of mystery. The famous "ghost ship" is the classic material of the writer's fictional voyage stories. technology. At present, unmanned ships are in a period of rapid development. However, unmanned ships still face many technical bottlenecks that have not been resolved before they are launched for trial voyage and when they are operating on the water.

At present, unmanned ships are in a period of rapid development. However, unmanned ships still face many technical bottlenecks that have not been resolved before they are launched for trial voyage and when they are operating on the water.

[0003] Unmanned ships, as the name suggests, do not need human drivers to control them. Whether the emergence of the concept of "zero crew" is appropriate, there are different opinions in the industry. A reporter from the publication "Safety" once proposed the distance between the ideal and reality of "unmanned ships". It is proposed that if a ship suddenly catches fire and its location is unknown, according to the current level of technology, the operator of the unmanned ship will definitely give two instructions. One is the optimal method, that is, send a fire-fighting robot to find the exact fire point and extinguish it. The second is that if the robot cannot complete the fire extinguishing task, the ship will turn on the high-pressure water mist fire extinguishing system to complete the fire extinguishing task. There are two plans and one backup, which seem to have no defects, but there is one problem that cannot be avoided, even if the whole ship has Monitoring equipment, however, does not guarantee that the monitoring equipment has no blind spots. At this time, if a fire happens to be caught in the blind spot or is the source of the fire, neither of the two methods can be implemented. We can only watch the ship burn up and sink.
