The invention relates to the technical field of unmanned aerial vehicle signal detection, in particular to an image transmission signal detection method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining an image transmission signal of an unmanned aerial vehicle; determining a target time-frequency graph according to the graph transmission signal; performing frequency domain bandwidth detection on the target time-frequency graph, and determining whether the frequency domain bandwidth detection is satisfied or not; if yes, time domain feature detection is carried out to determine whether a reference signal meeting the time domain feature exists or not, and a signal in the same row as the reference signal is determined as a target signal in the target time frequency graph; and when the target signal exists, determining the target frequency corresponding to the target signal as the signal frequency of the target unmanned aerial vehicle. The method can be realized based on various general processors, after the target time-frequency graph is determined, time-frequency analysis is carried out on the graph transmission signal of the unmanned aerial vehicle by combining frequency domain bandwidth detection and time domain feature detection so as to determine whether the graph transmission signal accords with the corresponding signal feature, and thus the cost problem caused by hardware circuit detection is avoided.
本申请涉及无人机信号侦测的技术领域,尤其涉及一种图传信号检测方法及其装置、电子设备以及可读存储介质,该方法包括:获取无人机的图传信号;根据图传信号,确定目标时频图;对目标时频图进行频域带宽检测,确定是否满足频域带宽检测;若满足,则进行时域特征检测,以确定是否存在满足时域特征的参考信号,并在目标时频图中确定与参考信号同行的信号为目标信号;当存在目标信号时,确定目标信号对应的目标频率为目标无人机的信号频率。本方法可基于各类通用处理器实现,在确定目标时频图后,结合频域带宽检测与时域特征检测来对无人机的图传信号进行时频分析,以确定图传信号是否符合对应的信号特征,从而避免了硬件电路检测带来的成本问题。
