We use a different transmission method where binary Golay complementary pairs are sent simultaneously on the inphase and quadrature parts of the subcarrier, and compare the performance with existing method. Using our method, the radar obtains a pair of Golay sequences from only one echo, which reduces the ambiguity function sidelobes when the reflected signals are partially received, and fully exploits the property of Golay pairs.

我们采用将二位元格雷互补对以复数组合，发射时以调变正交载波的方式同时传送，并且将一个时段同时传送格雷互补对之方式，与一个时段仅传送一个二位元格雷互补序列比较，可使雷达仅接收一个回波即可得到一对格雷互补序列，以降低回波部份接收时之混淆函数旁峰，使格雷互补对之特性充分发挥。

This paper introduces the studies of the ultra-short Thomson scattering X-ray source at the accelerator laboratory of Tsinghua University in recent years. Properties such as the photon yield,the pulse length and time jitter of the produced photon pulse were predicted theoretically from the parameters of the electron bunch and the laser pulse,and the scattering angle. Preliminary experiments were successfully carried out with a 16 MeV backward-traveling-wave accelerator and the ns-Q switched laser provided by China Academy of Engineering Physics. This paper also introduces the 1.6-cell electron gun that was fabricated on site and the experiment with high RF power including the measurement of the electron bunche parameters. Based on these,we have designed an X-ray source,which is now under construction.
