本文提出基于压缩感知的被动式目标轨迹测绘算法，仅用少量观测数据一次性精确测绘出目标轨迹，减少了计算和通信开销，降低了能耗。-In this paper, a passive object trajectory mapping algorithm based on compressive perception is proposed. Only a small amount of observation data can be used to accurately plot the target trajectory, which reduces the computational and communication overheads and reduces the energy consumption.
