Description

Fully digital active array radar device and its operation method {Apparatus for Fully Digital Active Array Radar and the Operation Method Therefor}

The present invention relates to a fully digital active array radar device and an operating method thereof, and more particularly, by executing a simulated target scenario prior to an interlock test by a simulated target test equipment to internally generate and receive a simulated target signal, thereby interlocking the internal interlocking It relates to a fully digital active array radar device that is easy to test and an operation method thereof.

A radar device is a device capable of radiating electromagnetic waves to a target using an antenna having high directivity and then receiving a reflected wave reflected from the target to obtain target information such as distance to the target, direction, and shape of the target. am.

With the development of radar technology, antennas used in radar have also evolved from passive to active types. In addition, a radar device using such an active antenna is also evolving into a digital active array radar that digitally synthesizes beams in individual element units or subarray units in the form of forming beams in the conventional analog method.

Recently, in the case of an active array radar device being developed in Korea, a received signal is converted into an I/Q (In phase/Quadrature phase) digital signal in an individual element unit for high directivity, low side lobe level, rapid beam scanning, and low power characteristics. A completely digital method of converting and synthesizing beams is used.

On the other hand, in the case of a radar device, it is necessary to have a performance test mode function to frequently verify performance by simulating a real environment.

The goal of the effective test mode, that is, the simulated target test, is to check the performance of the radar by checking the interworking between the antenna part and the signal processing part of the radar.

This test is verified with simulated target test equipment, and at this time, three types of equipment, for example, signal processing unit, antenna unit, and simulated target test equipment, for which interlocking has not been verified, are tested simultaneously.
