A new waveform utilizing Costas sequence and interpulse frequency hopping (
FH) can be used as a good high-range resolution radar signal. The signal pr
ocessing using inverse discrete Fourier transform (IDFT) in the interpulse
Costas FH radar was studied. The principle of the interpulse Costas FH rada
r signal without the delay-Doppler coupling was analyzed. The influence of
target motion on synthetic range profile was discussed and simulated.
