orbit
编程仿真连续小推力实现GTO到GEO的三阶段转移过程,其中推力器的推力大小为0.8N,轨道机动的起始点为GTO的远地点。GTO轨道的升交点赤经为0度,近地点角距为90度。
GTO轨道: ph:185km,ah:35786km,i:28.5°,GEO轨道:h:35786km,i:0°。
卫星质量为6600kg,从GTO到GEO,采用5000s的推力器。取地球半径为6378km,g取值为9.8m/s^2(The three stage transfer process from GTO to GEO is realized by simulation and continuous small thrust. The thrust of the thruster is 0.8N, and the starting point of orbital maneuver is the apogee of GTO. GTO orbit RAAN is 0 degrees, 90 degrees for the argument of perigee.
GTO orbit: ph:185km, ah:35786km, i:28.5, GEO orbit: h:35786km, i:0.
The mass of the satellite is 6600kg, from GTO to GEO, using the 5000S thruster. The radius of the earth is 6378km, and the value of G is 9.8m/s^2)

最大似然
说明: 两种不同的假设:
H1 : 0 xn A fn wn ( ) cos(2 ) ( ) = ++ π θ n=1,2,…,N,f0 为规一化频率
H0 : xn wn () () = n=1,2,…,N
其中 w[n]是均值为 0,方差为 2 σ n 的高斯白噪声,A 已知,样本间相互
独立,信号与噪声相互独立; 相位θ 是随机变量,它服从均匀分布

1)改变输入信噪比(改变 A 或噪声方差均可),给定虚警概率,画出
输入信噪比与检测概率之间的理论曲线。(注意:理论检测曲线与样本
数有关) 2)改变样本数,用 Monte-Carlo 实验方法得出 PF=0.001 时输入信噪比
与检测概率之间关系曲线(至少三条),并得出结论。 3)改变 M-C 实验次数,样本数不变,用 Monte-Carlo 实验方法得出 PF =0.001 时输入信噪比与检测概率之间关系曲线(至少三条),并得出
结论(Draw the theoretical curve between input SNR and detection probability)
