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)

测距仪测距的过程中,由于受到仪器本身的系统误差以及外界环境影响,会造成测距精度的下降。为了提高测距的精度,我们需要对测距的结果进行改正,可以分为三种类型的改正:仪器常数的改正、气象改正和倾斜改正。(Rangefinder ranging process, due to systematic errors in the instrument itself and the external influences, ranging accuracy will result in a decline. In order to improve ranging accuracy, we need to correct the results of the distance, can be divided into three types of corrections: the correction instrument constant, meteorological correction and inclination correction.)
