| 摘 要： | 利用自行研制的武汉电离层探测系统,使用改进的相位编码脉冲串信号,对武汉天河机场上空的飞机目标进行了探测.通过对回波的相干积累和谱分析,获得了机场上空的飞机目标回波,再利用时频分析方法得到了目标视向速度随时间的变化,并以此估计了目标的飞行状态.实验验证了利用相位编码脉冲体制短波雷达探测高速飞行目标的可行性,提出可使用时频分析方法来获取目标的运动特征.

| Abstract: | The self-developed Wuhan ionospheric sounding system has used the improved phase coding pulse trains to detect the airplane targets over Wuhan Tianhe Airport.The echoes reflected from the airplane over the airport were gained after coherent integration and spectrum analysis.The time-frequency analysis can display the variations of the line-of-sight velocity with time and do help to estimate the flight regime of the target.The experiment has certified the ability of the high-frequency radar using phase codin... |
