high-resolution-one-dimension
高分辨率要求系统具有大的带宽,瞬时带宽的增加必将提高系统对硬件的要求,本文采用方便灵活的步进频率波形信号。脉间频率步进波形通过子脉冲载频的步进变化来获得大的有效带宽,使成像具有高分辨率,采用加窗和补零方法提高信噪比,但该信号对目标径向速度非常敏感。采用补零方法提高距离取样分辨率,使距离像细化,并用公式说明了补零只能提高距离取样分辨率,并不能改变频率步进信号的距离分辨能力。该信号波形对目标径向速度的敏感,使目标能量分散到邻近的距离单元造成距离分辨率下降,如果不事先进行速度补偿,直接对回波信号进行逆傅立叶变换,将使所成一维距离像发生频谱展宽,并伴有距离像发生平移。本文证明了当目标有径向速度时仍采用对回波信号直接进行逆傅立叶变换的方法将使一维距离像发生频谱展宽并伴有距离像发生频移,从而严重影响了一维距离像的质量。(high-resolution requirements of the system with large bandwidth, the increased instantaneous bandwidth will improve the system of hardware, In this paper, a flexible and convenient step frequency signals.

FDTD_microstrip
分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)

GA-DF2
说明: 利用GA遗传算法解决欺骗函数最优问题,具体问题描述如下,如有问题请与我联系(The deceptive functions are a family of functions in which there exists
low-order building blocks that do not combine to form the higher-order
building blocks. Here, a deceptive problem that consists of 25 copies of
the order-4 fully deceptive function DF2 is constructed for this paper.
DF2 can be described as follows:
f(0000)=28 f(0001)=26 f(0010)=24 f(0011)=18
f(0100)=22 f(0101)=6 f(0110)=14 f(0111)=0
f(1000)=20 f(1001)=12 f(1010)=10 f(1011)=2
f(1100)=8 f(1101)=4 f(1110)=6 f(1111)=30
This problem has a maximal function value of 750.)
