。给出了时域滤波的基本原理以及通常采用的
IIR 椭圆地物杂波滤波器的设计方法。重点研究了回归滤波器这一时域滤波算
法。从正交多项式的拟合出发,给出了回归滤波器抑制地物杂波的基本原理及
其滤波实现过程。通过对回归滤波器的计算复杂度的研究,寻找使回归滤波器
计算量最小的正交多项式。分析了回归滤波器频率响应特性,比较了回归滤波
器与IIR 椭圆地物杂波滤波器的计算复杂度。利用仿真的雷达信号,分析了回
归滤波器的地物杂波抑制性能。回归滤波器实际上是一高通滤波器,它在滤掉
低频地物杂波的同时,对落在滤波器阻带内的天气回波信号同样会造成衰减。
在天气回波信号谱宽固定的情况下,通过改变天气回波信号的平均多普勒频率,
分析了回归滤波器对它的衰减情况。在基于一组实际采集的雷达信号的基础上,
给出了回归滤波器的地物杂波抑制比随着滤波器阶数的变化情况。(Firstly, this dissertation introduces the research background and significance of
ground clutter suppression, analyzes the characteristics of the ground clutter and
weather signals in the Doppler weather radars and simulates Doppler radar echo
signals (It includes ground clutter, weather echo signals and the mixture of them).
The simulated signals are used later to study the time and frequency domain ground
clutter suppression.
Secondly, this dissertation talks about the time domain filtering, gives the basic
theory of time domain filtering and describes the design method of the usually used
fifth-order elliptic infinite impulse response (IIR) ground clutter filter. In the time
domain, the work focuses on the regression filter. From the orthogonal polynomials
fit, this dissertation gives the basic theory of the regression filter for ground clutter
suppression and the filtering process using a regression filter. Through the study of
the computational complexity of regression)

数字密码引爆器的输入描述:1、 在开始输入密码以前的等待状态,首先要按READY键,表示目前准备就绪,可以输入数字密码;2、 当引爆事件发生后,应该回到等待状态,设置WAIT_T键;3、 如果输入密码不正确,此时要操作READY和WAIT_T是不起作用的,必须由设计人员重新设置到等待状态,设置SETUP键,SETUP为内部按键,操作人员应该不能接触;4、 确定密码输入后,要设计一个点火按键FIRE;-digit passwords detonated"s input Description : one at the start and enter the password before the wait state, according to First READY button, now ready to be imported into digital code; Two, when detonated after the incident, should wait for the state to set up WAIT_T bond; three, if a password is not correct, this time to operate READY WAIT_T and is non-functional, the design must be re-installed to wait for the state, set up SETUP button SETUP internal keys, the operator should not contact; 4 to determine the password, to design a FIRE- ignition keys;
