A Study on the Enhancement of Detection Performance of Space
Radar sensors are used for space situational awareness (SSA) to determine collision risk and detect re-entry of space objects.
The capability of SSA radar system includes radar sensitivity such as the detectable radar cross-section as a function of
range and tracking capability to indicate tracking time and measurement errors. The time duration of the target staying in
a range cell is short; therefore, the signal-to-noise ratio cannot be improved through the pulse integration method used in
pulse-Doppler signal processing. In this study, a method of improving the signal-to-noise ratio during range migration is
presented. The improved detection performance from signal processing gains realized in this study can be used as a basis for
comprehensively designing an SSA radar system
