摘　　要：针对分布式多输入多输出雷达信号级融合检测的通信带宽过大的问题,提出了一种信号级量化融合检测算法。文中首先对量化融合检测算法进行了理论推导,给出了量化后融合中心的判决准则;然后,以最大化巴氏距离为目标构建了量化准则,并且给出了求解量化门限的迭代步骤。仿真结果表明:该方法在将通信带宽降低一半的情况下,依然能够获得与信号级融合检测算法相同的检测性能。A quantized signal fusion detection method is studied to solve the problem of overlarge communication bandwidth causedby the signal fusion detection method of distributed multiple-input multiple-output （ MIMO） radar. Firstly, the theory derivation ofthe quantized signal fusion detection method is performed, and the detection criterion in the signal fusion center after quantization isgiven. Then, quantization criterion is constructed with the purpose of maximizing the Bhattacharyya distance, and the iterativesteps to obtain the quantization gates are listed. Numerical results indicate that this method can achieve the same detection performanceas the signal fusion detection method with a half communication bandwidth.
