摘　　要：与宽带单基地雷达相比,宽带T/R-R双基地雷达有诸多优势。研究了宽带T/R-R双基地雷达目标的特征提取问题,利用两个站同时观测到目标一维像,分别提取了目标单站一维像对应的距离与双站一维像对应的距离和;结合双基地雷达目标定位方法,给出了目标长度和姿态角的估计方法,仿真分析了目标位置和基线长度对估计精度的影响;在此基础上,通过多次观测,给出了目标长度、目标姿态角以及姿态角平均变化率的估计方法。最后,仿真结果表明了所提方法的可行性和有效性。Compared with a wideband monostatic radar, a wideband T/R-R bistatic radar has many advantages. In this paper, a method for target feature extraction in the wideband T/R-R bistatic radar is studied. With a wideband signal, the T/R and R receivers are used to obtain the lengths and the locations of the monostatic High-range resolution profile （HRRP） and the bistatic HRRP separately. Combined with the target localization method, the target length and the attitude angle are estimated, and the simulation results are provided for analyzing the effect of the target location and baseline length on the estimation accuracy. Based on the sequential observation, the target length, target attitude angle and its change rate are estimated, and the simulation results well validate the theoretical analysis.
