摘　　要：针对传统检测方法在检测和跟踪微小卫星时存在若设置的检测门限较高可能造成目标丢失、若设置的门限较低则会导致大量虚警的缺陷,将检测前跟踪的基本理念运用到具体场景中,提出了一种对微小卫星的检测前跟踪(TBD)方法;建立了红外传感器观测模型,推导了有关检测前跟踪算法,设计了粒子滤波的具体实现步骤;最后进行了仿真实验,验证了模型和算法的有效性。Aiming at the defects of traditional detection methods in detecting and tracking micro-satellite that if the detection threshold is set too high,the target may be lost,while if it is set too low,a large number of false alarms will arise,this paper proposes a Track-Before-Detect(TBD)algorithm for micro-satellite by applying the basic concept of TBD to specific scenes.The observation model of infrared sensor is established,the TBD algorithm is deduced,and the specific implementation steps of particle filter are designed.Finally,simulation experiments are carried out to verify the effectiveness of the model and algorithm.
