| 摘 要： | 根据空间光调制器的相位调制作用，提出了一种灰阶纯位相匹配滤波器编码方法。计算机仿真和光学实验结果均表明该方法在相关峰值、信噪比和峰相关能量比等方面比二元纯位相编码方法均有较大提高。另外还给出了相关峰的位置变化规律，有利于对目标的定位。

| Abstract: | A kind of coding method of gray-scale phase-only matched filter according to the phase modulation property of the spatial light modulator has presented. Both the results of the computer simulation and the optical experiment indicate that compared with the binary phase-only matched filter, this method has a great improvement on the correlation peak, the signal-to-noise ratio and the peak-to-correlation energy ratio. In addition, the rules of the correlation peak position was given ,which is helpful for the locating of the target. |
