中文摘要	用于探测火星电离层的星星间无线电掩星技术较以前的星地间探测技术相比,有可接收高信噪比的信号、掩星发生次数多且覆盖范围大和反演精度高等优点,首先介绍了两颗卫星的运行轨道以及在一定时间内两星间所有掩星事件的仿真结果,论述了利用无线电掩星数据进行火星电离层反演的理论,模型及相应的计算流程,并结合火星电子密度模型模拟的原始载波相位数据,反演计算了电离层电子密度剖面.反演结果和模型值符合很好,从而表明了该方法的优越性和可行性.
英文摘要	Satellite-to-Satellite radio occultation technique is used to explore Martian ionosphere. Comparing with Satellite-to-Earth radio occultation technique, this technique is better. It has the ability to receive high signal-to-noise ratio radio signal and it can acquire more accurate profiles in a wider range. First, the simulation of all occultation events based on two suitable simulated satellite orbits was introduced. It focused on the theory and model of ionosphere inversion from the occultation data and the computation flow. The electronic density profiles were derived from simulated occultation data. Using Martian electronic density model, the simulated occultation data was acquired. The inversion profiles are reasonable,and the results indicate that this method is advanced and reliable.
