Aiming at the signal bandwidth design problem for multi-target imaging task, a kind of multiple input multiple output ( MIMO) radar waveform design method is proposed. At first, the closed-loop feedback between the range profile and the signal bandwidth, which can design the mini-mum bandwidth of a transmitting signal that can distinguish each scatterer of the target in range di-rection, is established. Then, considering the request of beam patt and the bandwidth limitation, a waveform optimization model is established and solved. Therefore, the multi-target observation and the dynamic adjustment of the signal bandwidth are accomplished. In the end, the simulation re-sults prove the performance of the algorithm in a low SNR circumstance.

猎手变猎物 我们曾大张旗鼓地振兴京剧，什么硕士班，什么音配像，但20多年的实践证明，京剧依然垂暮衰微。再如我们投入巨额经费人工繁育大熊猫，但野外放生的结果令人沮丧。熊猫的退化是命中注定的，是造化使然。人工繁育的熊猫使原本就不断退化的它们，差不多已沦为了人类的宠物。 在100万年前的更生世中晚期，与剑齿象一样剽悍的大熊猫，已经广布于我国南半部，它的古代名称有貘、白豹、林云等。当时的熊猫敏捷凶
