To demonstrate the pulse compression capability, a binary
phase-coded signal at 10 GHz using a pseudo-random bitsequence (PRBS) as the coding signal is generated. The PRBS
has a bit rate of 1 Gb/s with a length of 128 bits. Fig. 10(a)
shows the generated binary phase-coded signal with a pulse
duration of 128 ns. Fig. 10(b) shows the autocorrelation of
the binary phase-coded microwave signal. A compressed pulse
is obtained. The autocorrelation peak has a full-width at halfmaximum
(FWHM) of about 0.945 ns, thus the compression ratio
is about 132. The peak-to-sidelobe ratio (PSR) in Fig. 10(b)
is about 9.68, which is greater than those reported in [8]–[10]
thanks to the accurate π phase shift in the phase-coded pulse
sequence
