Description

Radar test equipment and method

The present invention relates to a radar testing facility and method, and more particularly, to a radar testing facility and method capable of testing the performance of a radar operated in the air.

Unlike optical images, synthetic aperture radar (SAR) images have the advantage that they can be acquired in all weather regardless of climate and time, so they can be used in various fields such as surface information identification, maritime surveillance, and disaster surveillance, as well as military purposes. is being used in The main loading platform of SAR equipment is a rapidly moving platform such as a satellite or an aircraft, which collects and synthesizes signals for a certain period of time to form an image. Therefore, compared to the radar system operated on the ground, the SAR equipment has great limitations in the performance analysis of the system before being mounted on the actual platform.

A flight test is required to analyze the performance of such SAR equipment, but because it takes a lot of time and money, a radar test that simulates the air-to-ground in the surrounding environment is performed while driving the SAR in a vehicle and driving a high-position bridge or road. are doing However, there is a difficult problem in implementing the same test environment as the actual air or space environment in which the SAR is operated by various structures installed on the ground. In addition, due to the change of the test environment on the ground, it is difficult to repeat the test under the same conditions, and there is a limit to obtaining accurate information about the test environment (the exact location of the radar during measurement, the distance/size/material from the detection target, etc.) . In particular, since meteorological conditions continuously change on the ground, there is a problem in that the test cannot be performed at a high speed without the influence of weather conditions, such as operation on a satellite.

Hereinafter, a radar test method according to an embodiment of the present invention will be described.

In the radar test method according to an embodiment of the present invention, the process of preparing a movement path of the radar using a cable in the air spaced apart from the ground, the process of installing the radar on the cable, and moving the radar, and improving the performance of the radar It may include testing. Here, the radar is an air-to-ground radar mounted on a satellite or an air vehicle and operated in the air, and may include a synthetic aperture radar.

First, it is possible to prepare a test facility for testing the performance of the radar on the ground. At this time, it is recommended that the test facility be provided in a place where the radar performance can be tested under certain conditions. For example, a test facility can be prepared by installing a pylon in a mountainous area where vehicles do not pass, connecting a cable to the pylon to separate it from the ground, and installing a cradle capable of mounting a radar on the cable.

In addition, a reference target for adjusting the zero point of the radar and a test target for testing the performance of the radar may be installed on the ground, and the reference target information of the reference target and the test target information of the test target may be prepared. In this case, the reference target information and the test target information may include information such as distance, size, and material for each target.

The radar can be mounted on a cradle to test the radar. At this time, the operator may use a separately provided working device to move to a position where the cradle is installed, and then mount the radar on the cradle. In addition, the operator may lower the cradle or part of the cradle installed on the cable, and mount the radar on the cradle from the ground.

After the radar is mounted on the cradle, the zero point of the radar can be adjusted using the reference target installed on the ground. In this case, after moving the cradle to a predetermined position, a signal, for example, a radar signal, may be transmitted to the reference target, and a signal reflected from the reference target, for example, target information may be received. In this case, the radar may receive, in real time, information necessary for radar signal processing, such as the position, movement speed, posture, etc. of the cradle measured from the measuring device installed on at least one of the cradle, the support, and the cable through the communication device. Here, information such as the position, movement speed, and posture of the cradle may be the same as information on the position, movement speed, and posture of the cradle of the radar to be tested. In this case, the communication device may transmit information such as the position, movement speed, and posture of the cradle or the radar to the radar signal processing device provided on the ground in real time. And it is possible to adjust the zero point of the radar by analyzing the received target information.

When the zero point of the radar is adjusted, the power unit can be operated to move the cradle and the radar, and the test target information for the test target can be obtained by operating the radar. And when the test target information is obtained, the acquired test target information and the test target information prepared in advance may be compared, and the performance of the radar may be corrected according to the comparison result. In addition, it is possible to acquire test target information for the same test target while moving the radar while maintaining the same conditions, such as the moving speed and altitude of the radar as in the previous test. Such tests can be performed until the radar's performance is accurately calibrated.

In addition, in the process of testing the performance of the radar, at least one of the altitude at which the radar is disposed, the moving speed and the angle of the radar may be adjusted, and test target information about the test target may be obtained.

If the performance of the radar operated in the air is tested in this way, the influence on the surrounding environment is minimized and repeated tests are possible under the same conditions. In addition, since the performance of the radar is tested while moving the radar along a fixed path like a cable, the position, movement speed, and attitude of the radar can be accurately grasped. Through this, the performance of the radar can be understood more accurately.

As such, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention, and various combinations between the embodiments are possible.
