余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

说明：  自己根据<最优化理论与基础>课本编的matlab程序 最优化问题求解: 牛顿法 自助输入目标函数及其梯度(Optimization: Newton Method Type in objective function and its gradient by yourself.)

说明：  合成孔径雷达点目标成像仿真（RD算法），条带模式(SAR point target imaging simulation (RD algorithm))

目标作匀速圆周运动，包括kalman和最小二乘滤波，亲自调试通过的，可出x，y，误差(Target for uniform circular motion, including the least squares filtering kalman and personally through debugging, and can be the x, y, error)

对bpsk,qpsk,16qam,64qam进行数字调制和解调(digital modulation and demodulation to bpsk, qpsk, 16qam, 64qam)
