Abstract

The invention discloses a two GHz bandwidth digital radio frequency memorizer and a storage method. The memorizer comprises a broadband analog/digital converter (ADC), a radio frequency processing field-programmable gate array (FPGA) and a storage pool. The radio frequency FPGA comprises a serial/parallel converting unit. The ADC is connected with the input end of the serial/parallel converting unit, and the output end of the serial/parallel converting unit is connected with the storage pool. The two GHz bandwidth digital radio frequency memorizer and the storage method are mainly used in the technical field of radar radio frequency emulation and have the capability of collecting and playing back high-speed data, the functions of data collecting, storing, transmitting, playing back and the like can be achieved flexibly, the problem that an existing DRFM system bandwidth is not enough can be solved, and the capability and speed of radio frequency signal storing are improved.

Description

technical field [0001] The invention relates to the technical field of radar radio frequency simulation, in particular to a 2GHz bandwidth digital radio frequency memory and a storage method. Background technique [0002] At present, with the advancement of science and technology and the diversified development of modern national defense technology, in the field of national defense science and industry, facing the actual needs of modern digital warfare, new requirements have been placed on technologies such as radar signal processing and system simulation, requiring radar signals to have Wider bandwidth, the bandwidth can reach 2G, therefore, the bandwidth of hundreds of megabytes in the original technology can no longer meet the above requirements, in order to solve the above problems, in the prior art, the complex hardware structure and multiple signal processing designs meet the above requirements , but at the same time, the problem is that due to the increasing difficult...
