Delay signal processing method based on jump processing

Abstract

The invention provides a delay signal processing method based on jump processing, and relates to the technical field of remote detection, and the method comprises the following steps: obtaining a delay time value of a signal transmitting device; judging whether the delay time value of the signal sending device is not less than a preset time difference value frequently, and if so, selecting a device arranged between the signal receiving device and the signal sending device as an intermediate device; the intermediate device pre-processes the original signal and then transfers and transmits the original signal to the signal receiving device; the signal receiving device judges whether the original signal arrives earlier than the preprocessed signal; if yes, correcting the original signal in combination with the preprocessed signal; and otherwise, predicting the original signal according to the preprocessed signal. The method is simple and reasonable, original signals are forwarded in a skipping mode through the intermediate device, the original signals possibly having signal delay can be preprocessed, loss caused by signal delay is reduced, and the application range is wide.

Problems solved by technology

[0005] However, the above-mentioned remote sensing detection method still has the following disadvantages: if the space probe detects the signal and sends the data back to the ground, it is possible that the signal sent by the tiny satellite will be affected by interference due to the small bandwidth, causing the received information to be distorted. It will be blocked by obstacles, or it may be intercepted by other detectors, which will cause important detection information to leak or not be processed in time. All of the above can be summarized as signal delay, which may cause greater losses
