Description

SIMULATION INSPECTION APPARATUS AND METHOD FOR TESTING ELECTRONIC WARFARE PERFORMANCE OF RF SEEKER IN AIR-TO-AIR MISSILES The present invention relates to a simulated inspection device for checking the electronic warfare performance of a seeker and a method of operating the same. The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art. The conventional system inspection method for domestic guided missile RF seekers involved driving a target-simulating antenna with a motor so that the seeker would track the target antenna via RF frequencies. This method was primarily applied only to stationary targets, such as ships, land radars, and buildings, and the target was considered to be in a nearly stationary state relative to the missile's relative velocity. However, with the development of Boramae, the development of domestic air-to-air guided missiles is scheduled, and RF seekers are being considered as the primary option. The target of an air-to-air guided missile is an enemy aircraft, which has dynamic movements in the air and needs to be able to overcome electronic warfare (jamming, decoys, chaff, etc.) situations. Therefore, conventional methods for checking RF seekers cannot effectively simulate the dynamic movements of targets and electronic warfare, and thus have limitations in checking essential performance capabilities of RF seekers, such as anti-jamming and deception exclusion. The present invention proposes a new system inspection method to solve these problems. Figure 1 is a diagram illustrating a conventional explorer inspection method. FIG. 2 is a diagram illustrating the configuration of a simulated inspection device for checking the electronic warfare performance of an air-to-air guided missile RF seeker according to one embodiment of the present invention.
