Analysis of Communication Characteristics of Projectile-Carried Communication Jamming Object

Abstract

In order to facilitate the construction of projectile-carried communication jamming system model, this paper used the methods of literature search, classification and summary, and details sorting, deeply analyzing the communication characteristics of projectile-carried communication jamming object from seven aspects, including communication modulation mode, antenna type, antenna length, antenna transmission gain, sensitivity calculation, jamming tolerance, initial synchronization process and its characteristics. Then, the boundary conditions of projectile-carried communication jamming object were determined. In other words, the modulation mode of projectile-carried communication jamming object was 2FSK, the antenna type was whip antenna, the antenna length was 2 m or 2.4 m, the short wave antenna transmission gain was -10.5912 dBi, the ultrashort wave antenna transmission gain was -1.383 dBi, the jamming tolerance was 32% of the available frequency, and the initial synchronization time was calculated as 182 ms. The relevant conclusions lay a foundation for the follow-up study of projectile-carried communication jamming performance.
