波束形成DBF
说明: 声呐或者雷达系统发射信号后,通过波束形成算法对两个目标(方位分别为theta1、theta2)回波进行仿真,经过相位补偿,可以看出图像有两个波峰,波峰处指向性函数峰值最大,峰值所对应的的角度值即为目标的方位角。所以该程序对数字波束形成(DBF)的原理进行了仿真,适合初学者掌握阵列信号处理中数字波束形成的原理。(After the sonar or radar system transmits the signal, the echo of the two targets (the azimuth is theta1 and theta2 respectively) is simulated by the beamforming algorithm. After the phase compensation, it can be seen that the image has two peaks, the peak of the directivity function is the largest, and the corresponding angle value of the peak is the azimuth of the target. So the program simulates the principle of DBF, which is suitable for beginners to master the principle of DBF in array signal processing.)

JSteg
JSteg隐写技术matlab实现代码--基本思想:用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位,但若量化后DCT系数为0或者1,则不进行处理。(DCT系数的LSB嵌入)
(JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))
