Analysis to frequency synthetic sigh-resolution range profile based on linear FM stepped-frequency signal

The paper discusses that the high-resolution range profile is obtained by the frequency domain synthesis of linearly modulated stepped-frequency (LMSF). Firstly, it introduces that the method of frequency domain synthetic high-resolution range profile. And then it analyses that the velocity errors influence on the quality of high-resolution range profile using frequency domain synthesis technology. The results of simulation and experiments indicate that the frequency domain synthetic method of linearly modulated stepped-frequency (LMSF) is valid anddoable.
