单站高频雷达飞机目标探测的相关研究
Research on aircraft target detection by single station HF radar
摘要
Abstract
In order to expand the application field of compact High Frequency Ground Wave Radar(HFGWR),research has been conducted on the scenario of single-station compact HFGWR detecting aircraft targets.By exploring the impact of high-speed targets on the range spectrum and Doppler spectrum,as well as the challenges faced in obtaining the speed and range information of high-speed targets,the constraints of the linear Frequency Modulated Interrupted Continuous Wave(FMICW)waveform parameter design have been derived.Corresponding waveform parameters have been designed for long and short coherent accumulation time,and numerical simulations have been carried out.The research shows that under the condition of long accumulation time,the Generalized Radon Fourier Transform(GRFT)method is employed to eliminate the migration of range and Doppler frequency,achieving effective accumulation of target energy and accurate estimation of motion parameters;under the condition of short accumulation time,the signal-to-noise ratio of the target is significantly improved by combining time-frequency analysis with the greedy algorithm to first estimate the motion parameters of the target,and then compensate for the slow time signal of the range.The feasibility of single-station compact HFGWR detecting high-speed targets has been verified through theoretical derivation and numerical simulation,and a theoretical foundation has been laid for subsequent field tests.关键词
