Problems solved by technology
[0002] Modern radar equipment, electronic warfare equipment, and communication equipment have many working systems and complex functions. To complete the research and development and functional inspection of the whole machine requires many indoor tests and multiple field tests. However, field tests are expensive, difficult to coordinate, and affected by weather and The site and other conditions are limited, and the experimental data is very valuable
Some problems encountered during the test can only be solved by reproducing the scene, but the environmental conditions of the field test are unique and cannot be accurately reproduced

The invention discloses a single-channel radio frequency signal acquisition and playback system, which includes a control module, a local oscillator unit, a data acquisition system connected to the control module, a signal playback system, and a signal storage unit; the data acquisition system includes successively connected signal conditioning units, The down-converter, the signal acquisition module, and the signal playback system include a digital-to-analog conversion unit, a frequency extension unit, and a power amplification unit connected in sequence. The signal acquisition module is connected to the digital-to-analog conversion unit through a signal storage unit, and the local oscillator unit is respectively connected to the down-converter , The frequency extension unit is connected. The invention performs analog down-conversion on the received broadband radio frequency signal, and can sample and digitally store the converted analog intermediate frequency signal. According to actual needs, the system can perform full-real radio frequency playback on the stored signal, and can also perform signal software Playback and analysis processing, realizing the acquisition, storage, processing and playback of broadband signals and other functions.
Description
technical field [0001] The present invention relates to the technical field of radio frequency, in particular to a single-channel radio frequency signal acquisition and playback system. Background technique [0002] Modern radar equipment, electronic warfare equipment and communication equipment have many working modes and complex functions. It requires many indoor tests and many field tests to complete the research and development and functional inspection of the whole machine. However, field tests are expensive, difficult to coordinate, and subject to weather and Due to the limitations of the site and many other conditions, the experimental data is very valuable. Some problems encountered in the test process can only be solved by reproducing the scene, but the environmental conditions of the field test are unique and cannot be accurately reproduced. [0003] In view of the above situation, the more accurate method at present is to record the data obtained from the field t...
