一种求解雷达目标冲激响应的并行算法

雷达目标的冲激响应是目标识别中的一种重要手段，可以从冲激响应中提取目标的各种特征，如目标的谐振频率等。为了实时地获得目标的冲激响应，本文提出了一种基于共轭梯度法的并行算法，同时改进了共轭梯度法的终止选代条件。经计算机仿真及对实测数据的计算，证明了这种方法的有效性。

A Parallel Algorithm for Obtaining the Impulse Response of Radar Targets

In target identification it is often desired to determine the impulse response of thetarget from which various features of the target can be extracted. A parallel algorithm basedon conjugate gradient method has been proposed to obtain the impulse response in real time,and the improvement of the iterative termination conditions for the conjugate gradient. Thegood agreement between the estimated and theoretical impulse responses shows that the algorithm is feasible for determining the impulse response of a target under low RSN.
