Narrow-band Radar Data Processing And Analysis Of Space Target Rcs

For limit of bandwidth, the information of target feature is very limited, which are from the narrowband radar echo of target. So that the data of narrowband radar can't be usually use of goal recognize. But the developing of broadband radar are starting just now in our nation. For satisfaction further measure request of target feature in experimentation task, we must dig thepotential of existing measure equipment so as to catch further target feature.The LM-XXX radar is the first long-distance radar which is provided with the target feature measure function. This article managed the RCS data of sputnik which were measured by that narrowband radar. Managed software were workout and pretreatmenting, data amalgamation and RCS calculation were achieved . Basing on the RCS sequence, analysed the target feature of some space goal.Calculated the RCS data using of data Statistic method and received the Statistic RCS feature of space goal.Analysed the imaging of the space goal using of ISAR method and equalized the high speed movement.Using wavelet analyzing method , combining FFT, estimated the wavelet power chart of the RCS time sequence, received the time-frequency feature. On the otherhand, received the periods feature of the spin space goal.
