主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(Graduate study do not to upload copyrighted controversial content and Trojan code and agent software to access foreign sites)

Synthetic aperture radar imaging provides high resolution
images of large areas. The intensities of pixels in a SAR
image are based on the spatial orientation, roughness, and
dielectric constant of the surface imaged.
SAR is an active sensor, transmitting its own energy, and
then measuring the return scattered by the earth抯 surface
back to the satellite抯 antenna. SAR processing is the
transformation of raw SAR signal data into a spatial image.
In this communication, we present a contribution
concerning implementation of a SAR image formation with
the IDL language. This process is performed in a frequency
domain correlation of the received signal including range
compression, range migration, and azimuth compression.
The output is the final step in which the data is transposed
back into its original format and written to an output file.
