Abstract

The invention relates to an internal self-test system of a short-wave prognosis selector, comprising an FPGA control circuit and a pre/post-selector filter circuit electrically connected with the FPGAcontrol circuit. The FPGA control circuit is electrically connected with a main control unit of an external short-wave radio station through a control interface. The system is characterized in that the self-test system further comprises a self-test signal shaping circuit, a conversion circuit and a self-test signal testing circuit electrically connected with the FPGA control circuit. The internalself-test system of the short-wave prognosis selector of the invention is simple in structure, reasonable in design, small in volume, low in cost, fast in speed, high in reliability, fast in frequency hopping speed, low in power consumption, low in noise, good in frequency selectivity, stable and reliable in operation, and can effectively improve the technical index and electromagnetic compatibility of the short-wave radio station.

Description

technical field [0001] The invention belongs to the technical fields of automatic control, quality inspection, isolation technology, frequency hopping and spectrum spreading in modern short-wave communication systems, and in particular relates to an internal self-inspection system of a short-wave pre / post selector. Background technique [0002] Today's electromagnetic signals are increasingly dense and complex, and the requirements for anti-jamming capabilities of communication countermeasure equipment are getting higher and higher. As a new generation of communication countermeasure equipment, shortwave frequency hopping radio has strong anti-interference and anti-interception capabilities, which makes it show great advantages in modern electronic warfare. The short-wave pre / post selector is the key component developed for the new generation of communication countermeasure equipment. Among them: the pre-selector is placed at the front end of the radio receiver to filter ou...
