JPS63215984A - Automatic/semiautomatic tracking processor - Google Patents

Abstract

PURPOSE:To facilitate the resumption of automatic tracking after a target, such as a ship, passes a region wherein the automatic tracking is difficult by automatically changing over the automatic tracking to semiautomatic tracking that is not related to radar video when the target passes said region. CONSTITUTION:Receiving radar video signals and radar bearing signals, a target detecting unit 11 digitizes the video signals with regard to a bearing and a range and extracts target data. A semiautomatic tracking region memory 14 stores the dead region of a radar and a region wherein automatic tracking is difficult, for example, a region wherein there is much sear clutter or rain and snow clutter or the like and feeds the data of those regions to an automatic tracking processing unit 12 and a semiautomatic tracking processing unit 13. The processing unit 12 and a semiautomatic tracking processing unit 13. The processing unit 12 automatically tracks a target on the basis of the target data from the target detecting unit 11. When the target is judged to enter the region wherein the automatic tracking is difficult by comparing the target data from the target detecting unit 11 and the data from the memory 14 with each other, automatic tracking data are fed to the processing unit 13 and the automatic tracking is temporarily changed over to semiautomatic tracking. Thus, since the automatic tracking is automatically changed over to the semiautomatic tracking and tracking is continued, the automatic tracking can be resumed without troubling an operator after the regions are passed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device that automatically tracks a target such as a ship using a radar installed on land at a port or the like.

(Prior Art) Conventionally, as shown in FIG. 2, this type of device includes a target detection section 21 that extracts target data from a radar video signal, and a target detection section 21 that detects a target based on the target data extracted by the target detection section 21. It was composed only of an automatic tracking processing section n that automatically tracks.

(Problem to be solved by the invention) Therefore, targets such as ships may be located in areas where they are blind spots for radar,
When navigating in areas where automatic tracking is difficult due to a lot of reflections from the sea, rain and snow, automatic tracking of the target fails, so automatic tracking has to be restarted from the beginning after the target passes through such an area. was there.

(Means for Solving the Problem) In order to solve this drawback, the present invention automatically changes automatic tracking to semi-automatic tracking that is not related to radar video when a target such as a ship passes through an area where automatic tracking is difficult. This will be explained in detail below with reference to the drawings.

Note that the semi-automatic tracking referred to here is a tracking method that is neither automatic nor manual tracking.9 For example, the amount of movement of the target per unit time is calculated based on initial data such as the actual target's position, speed, and course. , is a target tracking method that calculates the subsequent position of the target from moment to moment, and can perform tracking processing as if it were being tracked based on moment-to-moment information about the actual target.

(Example) FIG. 1 is a basic configuration diagram of an embodiment of the present invention.

The target detection section 11 receives the radar video signal and the radar position signal as input, extracts a target echo of a ship, etc., and outputs it to the automatic tracking processing section 12 as target data. The semi-automatic tracking area storage unit 14 stores data on areas where automatic tracking is difficult, such as areas that are radar blind spots, areas with a lot of sea surface reflection, rain and snow reflection, etc. is output to.

The automatic tracking processing unit 12 automatically tracks a target such as a ship based on target data from the target detection unit 11 and outputs tracking data. During this tracking process, the automatic tracking processing section 12 compares the automatic tracking data with area data from the semi-automatic tracking area storage section 14.

It is determined whether the target has entered the semi-automatic tracking area. When it is determined that the automatic tracking target has entered the semi-automatic tracking area, this automatic tracking data.

The signal is sent to the semi-automatic tracking processing section 13, and automatic tracking is switched to semi-automatic tracking.

Further, when this target passes through the semi-automatic tracking area, the tracking data is transferred from the semi-automatic tracking processing section 13 to the automatic tracking processing section 12.
, and automatic tracking will resume.

When the semi-automatic tracking processing unit 13 receives tracking data (position, course, speed, etc.) from the automatic tracking processing unit 12, the semi-automatic tracking processing unit 13 performs processing based on the input tracking data, regardless of the target data from the target detection unit 11. , start semi-automatic tracking. Also, semi-automatic tracking data.

In the semi-automatic tracking processing section 13, the semi-automatic tracking area storage section 14
When the area data is out of the area, the area data is returned to the automatic tracking processing section 12 in order to automatically restart automatic tracking. This is done by sending and switching tracking data from the semi-automatic tracking processing section 13 to the automatic tracking processing section 12.

(Effects of the Invention) As explained above, even when a target such as a ship is navigating in an area where automatic tracking is difficult, the tracking is automatically switched to semi-automatic tracking and tracking continues. This has the advantage that automatic tracking can be restarted without bothering the operator.
