An improved integration method is applied to detect dim debris targets in this paper. The algorithm makes full use of prior orbit information to reduce motion uncertainty, and then adopts the Hough line transform to integrate echo energy from multiple pulses. Thus, the detection capability for small-size space debris in the low earth orbit can be effectively improved. The proposed method is easy to...
Orbital debris in low-earth-orbit poses an increasing threat to humanpsilas space action. Spaceborne radar detection technique is a powerful complementarity for ground based radars or optical telescopes. The necessity of orbital debris detection using spaceborne radar is discussed; the design of spaceborne radar system is deeply studied on many aspects including operation frequency band, antenna type,...
