摘要
自主侦察是无人机载光电载荷的一种自动化、智能化侦察模式,参数计算则是自主侦察应用的前提。首先介绍了无人机载光电载荷的自主侦察模式;然后对该模式无人机自动巡航飞行速度和飞行高度,光电载荷的传感器视场角、俯仰角、扫描角速度、扫描角度范围等参数进行了计算,并分析了各个参数的物理意义及相互关系,以及对目标识别率、侦察时间等自主侦察效果的影响;最后举例进行仿真计算和分析,并指出在实际应用中存在的问题,为该模式的实际应用提供了理论依据。
Autonomous reconnaissance is an automatic and intelligent reconnaissance mode of UAV-borne photoelectric payload.Parameter calculation is the premise of autonomous reconnaissance application.The autonomous reconnaissance mode of UAV-borne photoelectric payload was first introduced,then the flight speed and altitude of autonomous UAV cruise,the sensor field angle of view,pitch angle,scan speed and scan angle of photoelectric payload were calculated,the physical meaning and relationship of each parameter were analyzed,and the influence of each parameter on target recognition rate and recon time was analyzed.Finally,simulation calculation and analysis were carried out with examples,and the existing problems in practical application were pointed out,which provided a theoretical basis for practical application of this mode.
