Description

technical field [0001] The invention relates to the technical field of signal detection, in particular to a method, device, terminal equipment and storage medium for detecting ultrashort wave weak signals in a high-noise environment. Background technique [0002] The design technology of an ultrashort-wave weak signal detection algorithm is to receive the surrounding environment signals through the reconnaissance receiver, which includes strong signals at short distances and weak signals at long distances. The signal strength at short distances is generally relatively large and can be received However, after the weak signal at a long distance is attenuated by space, it is a very weak signal when it reaches the receiving antenna, and the signal strength is sometimes submerged in the noise environment, so that the weak signal cannot be found according to the conventional detection algorithm Lead to the effect of affecting the reconnaissance. [0003] Therefore, it is necessar...
