Abstract

PURPOSE:To output the arbitrary radar image of either one of an air search radar video and a water-surface radar video by one video generating part by judging the antiaircraft radar video and the water-surface radar video by the discrimination of position data. CONSTITUTION:A position data discrimination part 1 inputs set target data 101 and altitude is judged on the basis of altitude data in an altitude judging circuit 11 and, thereafter, an antiaircraft/water-surface discrimination circuit 12 discriminates either one of an antiaircraft target and a water-surface target to output the same to a video generating part 2. In the video generating part 2, a radar video is generated on the basis of the inputted data by a target generating circuit 21. As mentioned above, from the target altitude data contained in the set target data 101, it is judged whether the target coincides with the air search or water-surface beam pattern concerned on the basis of an altitude standard in the position data discrimination part 1 and the target corresponding to each of beam patterns is selected to be outputted, displayed and simulated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radar signal simulating device, and more particularly to a radar signal simulating device capable of generating two systems of simulated signals: an airborne radar video and a surface radar video.

[Conventional technology]

Conventionally, this type of radar signal simulator outputs radar video signals using two independent video generators for air-to-air radar and water radar, and switches between them using a display.

[Problem to be solved by the invention]

The above-mentioned conventional radar signal simulator requires two independent video generators, and has the disadvantage that it lacks versatility and increases the scale of the device.

Another drawback is that the setting mouth motion information input to the airborne and waterborne video generators must also be input independently to the airborne and waterborne video generators.

[Means to solve the problem]

The device of the present invention is a radar signal simulating device that simulates radar video signals of two systems, an anti-aircraft radar and a surface radar. and a positional information identification unit that identifies whether the radar is a water radar, and a video generation unit that generates a radar video signal of an air-to-air or waterborne radar based on the result identified by the positional information identification unit. .

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a radar signal simulator according to the present invention. The configuration of the embodiment shown in FIG. 1 consists of a position information identification unit 1 that determines whether a radar video signal to be simulated is from an airborne radar or a surface radar based on the altitude information included in the set target information. and a video generating section 2 that generates a radar video signal of either an air-to-air radar or a water radar in accordance with the identification information of the position information identifying section 1.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

The position information identification unit 1 receives the set target information 101 and identifies its altitude information.

FIG. 2 is a diagram illustrating the operation of the position information identification section 1 of the embodiment shown in FIG. The conventional radar signal simulator has two independent radar video generators that generate two radar video signals corresponding to a beam pattern 31 for airborne radar and a beam pattern 32 for surface radar, and uses these separately to determine the target. By inputting information, display targets were generated according to each unique beam pattern and the output was simulated.

In contrast, in this embodiment, the position information identification unit 1 determines whether the target matches the corresponding air-to-air or water beam pattern based on the target altitude information included in the set target information, based on the altitude standard 3, It selects targets corresponding to each beam pattern and simulates the output display.

The position information identification unit 1 inputs the set target information 101, and the altitude determination circuit 11 performs altitude determination based on the altitude information.
After that, the anti-aircraft/surface identification circuit 12 identifies the target as either an anti-aircraft target or a surface target and outputs it to the video generator 2. In the video generation section 2, a target generation circuit 21 generates radar video based on the input information.

〔Effect of the invention〕

As explained above, the present invention makes it possible to output any radar image, either airborne radar video or waterborne radar video, with one video generation unit by determining airborne radar video and waterborne radar video by position information identification. It is versatile, and has the effect of reducing the scale of the device.
