Abstract

The invention relates to an automatic gain control system for proximity signals. The automatic gain control system comprises a coupler, a first-stage gain control module, a second-stage gain control module and a detector, the coupler, the first-stage gain control module and the second-stage gain control module are connected in sequence, and a signal is input from the coupler and output from the second-stage gain control module; the output end of the coupler is connected with the detector, and the output end of the detector is connected with the first-stage gain control module. The automatic gain control loop has the advantages that the starting speed of the automatic gain control loop is high, and the response time of the loop is within 100nS; the gain control dynamic range is large and is greater than 40dB; a digital circuit is not involved, and the influence of harmonic waves of a digital circuit clock on the sensitivity of the detector is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an automatic gain control system for a near-explosion signal. Background technique [0002] Proximity fuze is a device used on shells, rockets or missiles to detect the height of the projectile. Proximity signal refers to the radio signal containing the height information of the projectile received by the proximity detector. Explosion height refers to the time of explosion. The height of the projectile. At present, the accuracy of the explosion height of the proximity fuze is very low, and the consistency of the explosion height for different targets is very poor. Therefore, how to solve this problem needs to be considered at this stage. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, provide an automatic gain control system for the near-explosion signal, and solve the current existing problems. ...
