Changes-in-the-signal-to-noise-ratio
等间距线性阵列，阵元数M=8，阵元间距d= λ /2，等幅加权，目标方位φr =0°。产生空间白噪声矢量（复高斯分布）。
设阵列信号矢量元素s(m)=exp[j mψr]，其信号幅度为1，该阵元接收机附加的高斯噪声为n(m)=nmr+jnmi，其中实虚部均为独立同分布N(0, σ2)的高斯随机数，则该通道合成信号x(m)=s(m) + n(m)，其中信噪比为：
SNR = 10 lg[1/(2σ2)] = – 3 – 10 lg(σ2) (dB)
(The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted target azimuth φR = 0. Space generated white noise vector (complex Gaussian distribution). Let array signal vector elements s (m) = exp [j mψr], the signal amplitude, the element receiver additional Gaussian noise n (m) = nmr+jnmi which the real and imaginary parts are independent and identically distributed N ( Gaussian random numbers of 0, σ2), the channel the synthesis signal x (m) = s (m) the PPLS n (m), where SNR is: SNR = 10 lg [1/(2σ2)] =- 3- 10 lg (σ2) (dB))

ginput2
Do you still use GINPUT to graphically select points on current axes with the mouse? Try this one!
With GINPUT2 you can also:
1. ZOOM: in, out (double-click)!
2. PAN: when dragging!
3. DELETE: last selected point!
4. PLOT: while selecting! (optional, just input the line style!)
5. SCALE or GEOREFERENCE images! (optional, just input: true)
So, besides of selecting points in a more precise way (zooming) you can DIGITIZE(!!!) lines with the last two options, by simply using:
>> ginput2(true, .k )
Enjoy it!
