Abstract
An echo image generating device may be provided, which includes a signal acquiring module, a sensitivity setting module, and a screen generating module. The signal acquiring module may acquire an echo signal from a target object around a ship. The sensitivity setting module may perform a first sensitivity setting for the echo signal in a first range, and a second sensitivity setting for the echo signal in a second range without including the first range, the second sensitivity setting being different from the first sensitivity setting. The screen generating module may generate an echo image of the first range based on the first sensitivity setting, and generate an echo image of the second range based on the second sensitivity setting.
Claims14
An echo image generating device, comprising:
- processing circuitry configured to:
- acquire an echo signal from a target object around a ship;
- perform a first sensitivity setting for the echo signal in a first range, and a second sensitivity setting for the echo signal in a second range without including the first range, the second sensitivity setting being different from the first sensitivity setting;
- and
- generate an echo image of the first range based on the first sensitivity setting, and generate an echo image of the second range based on the second sensitivity setting,
- wherein the processing circuitry assigns a video slope to the echo signal in the first range and assigns a different video slope to the echo signal or an echo trail in the second range.
An echo image generating device, comprising:
- processing circuitry configured to:
- acquire an echo signal from a target object around a ship;
- perform a first sensitivity setting for the echo signal in a first range, and a second sensitivity setting for the echo signal in a second range without including the first range, the second sensitivity setting being different from the first sensitivity setting;
- and
- generate an echo image of the first range based on the first sensitivity setting, and generate an echo image of the second range based on the second sensitivity setting,
- wherein the processing circuitry places an indication of a position of the boundary between the first range and the second range on a screen including the echo image.
A method of generating an echo image, comprising the steps of:
- acquiring an echo signal from a target object around a ship;
- performing a first sensitivity setting for the echo signal in a first range and a second sensitivity setting for the echo signal in a second range without including the first range, the second sensitivity setting being different from the first sensitivity setting;
- generating an echo image of the first range based on the first sensitivity setting and generating an echo image of the second range based on the second sensitivity setting;
- and
- placing an indication of a position of the boundary between the first range and the second range on a screen including the echo image.
