(English Abstract)
Recently, as the technology of multi-function radar is developed, the radar deception technology of ballistic missiles is also developing. For some ballistic missiles, the propellant explodes in the air after the stage is separated, causing the warhead and many fragments to fly together, which lowers the multi-function radar¡¯s ability to engage ballistic missiles. Thus, there is a need for a radar system capable of operating a broadband waveform to intercept a warhead, by quickly discriminating between a high-speed warhead and fragments while retaining the existing target detection/tracking function. It is possible to find and intercept warhead among fragments by extracting the length of a target, using a broadband waveform and performing warhead classification using this. In this paper, we describe the process of performing the target detection/tracking function using a narrowband waveform such as doppler processing, pulse compression, threshold processing, and target processing and high-resolution target length extraction and phase diffraction correction for accurate length extraction using a wideband waveform to create a radar system that satisfies these requirements. Also, it shows the results of designing and implementing these functions with signal processing software and performing tests.
