Cognitive Radar Waveform Design Method under the Joint Constraints of Transmit Energy and Spectrum Bandwidth Open
The water-filling (WF) algorithm is a widely used design strategy in the radar waveform design field to maximize the signal-to-interference-plus-noise ratio (SINR). To address the problem of the poor resolution performance of the waveform …
High Velocity Motion Compensation of IFDS Data in ISAR Imaging Based on Adaptive Parameter Adjustment of Matched Filter and Entropy Minimization Open
This paper proposes a new high-velocity motion compensation method for intermediate frequency direct sampling (IFDS) data by adaptive parameter adjustment of a matched filter and entropy minimization. First, the influence of high-velocity …
Estimation of ballistic coefficients of space debris using the ratios between different objects Open
This paper proposes a new method to estimate the ballistic coefficient (BC) of low earth orbit space debris. The data sources are the historical two-line elements (TLEs). Since the secular variation of semi-major axes is mainly caused by t…
