Problems solved by technology

[0013] Therefore, a problem arises in conventional radar equipment: the operator of the radar system cannot recognize the target ship or the movement of the target ship for a certain period of time after switching the ranging scale
However, this approach is economically difficult to implement due to the high associated costs

Abstract

Methods and apparatuses process sensing signals. A method for redrawing a sensing image when a range is or has been changed, according to one aspect of the present invention, records the sensing image and outputs the sensing image to a display; records additional information displayed upon a screen and outputs the additional information to the display; computes a new image from the recorded sensing image using an image manipulation computer function, so that the computed image fits a new scale of the changed range, and recording the computed image; and computes changes to the recorded additional information to adjust the additional information to the new scale of the changed range, and records the computed additional information. The invention further discloses the radar equipment and analogous equipment.

Description

technical field [0001] The present invention relates generally to sensing systems such as radar and sonar systems, and in particular to methods and apparatus for processing signals in sensing systems when ranging is switched. Background technique [0002] Sensing devices, such as radar and sonar systems, are used to identify objects such as moving boats, vehicles, and aircraft, stationary systems and components, and also the altitude, velocity or acceleration of various objects, etc. For example, sensing devices typically transmit signals and receive outgoing signals from external objects, such as reflected or transmitted rays, echo signals, and the like. Sensing devices use these signals to obtain information about the objects associated with the signals. The information about the object may include a target image of the object, as well as related spatial data of the object. [0003] When switching a conventional radar device from one range (detection range) to another to...
