N2 - In the TOPSAR working mode, due to the limitation of system design, the pulse repetition frequency of the system is less than the overall bandwidth, which leads to the phenomenon of spectral aliasing and time-domain aliasing. There are a large number of operations such as matrix point multiplication, matrix and complex number multiplication in the three-step imaging algorithm process. At the same time, there are a large number of fast Fourier transforms, and there is a significant difference in the velocity in the azimuth and range directions.
