Multi-sensor system is becoming increasingly important in a variety of military and civilian applications. In general, single sensor system can only provide partial information about environment while multi-sensor system provides a synergistic effect, which improves the quality and availability of information. Data fusion techniques can effectively combine this environmental information from similar and/or dissimilar sensors. Sensor management, aiming at improving data fusion performance by controlling sensor behavior, plays an important role in a data fusion process. This paper presents a method using fisher information gain based sensor effectiveness metric for sensor assignment in multi-sensor and multi-target tracking applications. The fisher information gain is computed for every sensor-target pairing on each scan. The advantage for this metric over other ones is that the fisher information gain for the target obtained by multi-sensors is equal to the sum of ones obtained by the individual sensor, so standard transportation problem formulation can be used to solve this problem without importing the concept of pseudo sensor. The simulation results show the effectiveness of the method. Multi-sensor system is becoming more important in a variety of military and civilian applications.

小麦基因枪法遗传转化中幼胚组织培养很强的基因型依赖性问题,在很大程度上限制了转基因小麦的广泛应用,因此,探索建立旨在克服基因型障碍的小麦高效再生系统对于促进转基因小麦规模化应用具有重要意义。 本试验选用3个冬小麦材料H6756、H311和SP8581,研究了不同取材时期、不同诱导培养基、不同分化培养基和不同生根培养基对小麦幼穗离体培养的影响。结果表明,在护颖原基形成期至雌雄蕊原基形成期之间对
籼稻红莲型(HL)不育系和野败(WA)型不育系除花粉败育的特征不同外,两者还具有不同的恢、保特性。一些WA型不育系的保持系可能是HL型不育系的恢复系,而另一些HL型不育系的保持系又可能是WA型不育系的恢复系。关于利用保持系品种来比较研究这两类胞质不育系的恢复性遗传,尚未见报道。 本研究在明确了WA型不育系的保持系珍汕97B对HL型不育系粤泰A具有恢复力、HL型不育系的保持系粤泰B对WA型不育
