Simulation Method And Implementation Of Lander Radar Echo

The modern science and technology is developing rapidly,and the world’s major powers are actively developing deep-space exploration technology,which is also an important area of competitive power of major powers in the aerospace industry.The exploration of the universe by humans has never ceased.At present,from the data we have already grasped,Mars is the planet with the least difference from the earth.In deep space exploration,the best way to explore any planet is to land on the planet and explore further.However,if you want to better land on other planets,you will not be able to rely on sophisticated probe landing technology,and lander radar is more essential.The lander radar echo simulator is important for efficient research and development and testing of lander radar.It mainly studies the method and implementation of Mars lander radar echo simulation.The full text firstly describes the research status of the lander radar echo simulator at home and abroad,summarizes the advantages and disadvantages of domestic and foreign radar echo simulators,analyzes the development trend of radar echo simulation,and provides a radar for the lander of this article.Wave simulation provides research.Then,the basic theory of radar echo simulator for lander is analyzed and summarized.The characteristics of radar echo of the lander and the commonly used radar echo simulation technology are analyzed.Combined with the characteristics of the radar of the lander,the technical scheme of the playback structure is proposed in this paper.In addition,the key technologies are elaborated,which provides the design basis for the radar echo modeling of the lander in Chapter 3 and the design and implementation of the simulator system in Chapter 4.Then the radar echo modeling of the lander is introduced in detail and verified by simulation,which provides a theoretical basis for the design and implementation of the fourth chapter.Then it introduces the system design and implementation of the lander radar echo simulator,including the system software and hardware.The simulator system was further tested and verified,and the design results of the first four chapters were tested.And summarize the content of this article and look forward to future aspects where the system can be further improved.
