在微波辐射计信号处理过程中引入声光技术， 将线阵天线接收的延时（相干）信号经声光晶体调制激光信号， 采用光学傅立叶变换方法， 可以实时、同步地获得遥感图像， 并使微波辐射计的空间分辨率得到明显提高
The introduction of acousto-optic technology in the process of microwave radiometer signal processing, the delayed (coherent) signal received by the linear array antenna is acousto-optic crystal modulated laser signal, using optical Fourier transform method, the remote sensing image can be obtained in real time and synchronously The spatial resolution of the microwave radiometer has been significantly improved
