In the first and second chapter , spaceborne three - dimensional imaging altimeter is introduced briefly 文中第一、二章简要介绍了星载三维成象雷达高度计系统。
The main work of this thesis is to realize the 2d imaging processing of the experimental raw data , which lays a solid foundation for 3d imaging 主要的研究目的是实现星载三维成象雷达高度计的二维成象,为三维成象打下基础。
Zhang xiangkun ( aircraft design ) directed by : liu heguang , zhang yunhua this thesis is supported by the national 863 project " key technology of spaceborne three - dimensional imaging altimeter " 本论文课题是结合国家863计划课题“星载三维成象雷达高度计关键技术”而进行的。
A new real time internal calibration scheme resolved this problem . the high prf can improve the measurement resolution on large ocean wave , and the topex altimeter imposes 4200hz for prf , but the reason has not been published ( 5 )提出了大时带积高精度雷达高度计星上实时内校准方案,保证大时带积高度计可以实现在星上的闭环内校准工作。
The following are the main works : the maximum likelihood estimator ( mle ) was studied in detail , and the ocean return curve based on the sub - optimal maximum likelihood estimator ( smle ) was first obtained in china through the airborne flight experiment ( 2 )深入研究了星载雷达高度计最大似然跟踪算法,并完成了基于准最大似然算法的高度计跟踪器的研制,通过机载校飞实验,在国内第一次获得了基于准最大似然算法的海洋回波跟踪曲线。
