Abstract: The existing Track Before Detect（TBD） algorithms use non-coherent integration among frames.For enhance integration efficiency，a method is proposed which achieves detection by coherent integration.After connecting multi-frame echoes，selecting the azimuth，zeroing the noise and migration compensation，the method realizes coherent integration by FFT.Simulation result indicates that in contrast to the existing TBD algorithm this method can get wonderful STUN from less echo data.
Key words: multi-frame coherent integration, Track Before Detect（TBD）, weak target detection, migration compensation
摘要： 针对现有检测前跟踪（TBD）算法在多帧间积累时都使用非相参积累，积累效率较低的问题，对相参积累的TBD方法进行了研究。该方法在多帧回波数据下通过数据拼接、回波方位选取、噪声置零及走动补偿后利用FFT实现了帧间相参积累。仿真实验表明，相对现有的TBD方法，该方法能在较少帧的回波数据下实现良好的检测性能。
