研究了扫描速度和扫描发射极位置的联合估计问题。该方法利用天线主梁的均匀旋转运动，将其扫过若干个独立的接收器。基于非线性最小二乘估计(NLS)，建立了一个联合估计器。通过几个仿真实例，比较了所提出的估计量与cramer- rao下界(CRLB)的性能。(The joint estimation of scanning velocity and scanning emitter location is studied. The method USES the uniform rotating motion of the antenna main beam to sweep over several independent receivers. A joint estimator is established based on nonlinear least square estimation (NLS). Through several simulation examples, the proposed estimator and the performance of cramer-rao lower bound (CRLB) are compared.)
