摘　　要：为解决飞船返回舱再入段过程中由于等离子体引起的雷达目标丢失难题,利用太赫兹电磁波可以穿透等离子体的特点,设计了用于飞船返回舱再入段测量的太赫兹雷达。根据太赫兹发射机功率较低的现状,以及太赫兹电磁波大气传输损耗大的特性,采用机载太赫兹雷达进行飞船返回舱测量。分析结果表明,机载太赫兹雷达具有较好的工程可实现性。A Terahertz radar for the measurement of the spacecraft reentry capsule is designed to solve the missing problem of the radar target caused by the plasma during the reentering process of the spacecraft reentry capsule, by using the characteristics that THz waves can penetrate the plasma. Due to the low power of THz transmitter, and the high loss of THz waves in the atmosphere, the airborne THz radar is adopted to measure the spacecraft reentry capsule. The analysis results show that the airborne THz radar is easy to be realized in engineering applications.
