9. The digitized ultrashort wave training simulation system of claim 2, wherein the examination and evaluation module comprises two parts of question bank editing and efficiency evaluation, wherein the question bank editing collects theoretical knowledge of the radio station to establish a question bank, and organizes theoretical examination on the radio station of the personnel involved in training through random sampling, and the examination questions are selection questions and judgment questions; the essence of the efficiency evaluation is that a fuzzy mathematical change principle is used to perform normalized weight distribution on 6 factor performances of single machine training, networking training, anti-interference training, tactical simulation training, fault elimination and theoretical assessment of an evaluation object, and then comprehensive evaluation is performed.
10. The digitized ultrashort wave training simulation system of claim 1, wherein the ultrashort wave radio station training simulator is designed in an embedded manner, a minimum system is formed by an S3C6410 chip, and an auxiliary peripheral circuit module, a man-machine interaction module, a voice acquisition and processing module, a wireless WIFI module and a fault replaceable module are formed, so that the system is stable, strong in expansibility and convenient to upgrade.
