Device and method for generating baseband signal for radar transmission

Abstract

The invention discloses a generation device and method for radar transmitting baseband signals, and belongs to the technical field of radar system simulation. The device comprises a signal generation module, a signal processing module and a signal replaying module. The signal generation module generates an initial digital signal. The signal processing module is electrically connected with the signal generation module and conducts the caching and processing operations on the initial digital signal after preprocessing the initial digital signal. The signal replaying module converts a processed result digital signal into a result simulation signal and outputs the result simulation signal. A processing and caching unit in the signal processing module is an FPGA chip, and an SRAM is contained inside the FPGA chip, so that the SRAM is used for storing the signals, and an external storage needing to be adopted in the prior art is omitted. Therefore, the problem that due to the adoption of the external storage, the performance of the generation device of the radar transmitting baseband signals is affected is solved, meanwhile, the performance of the generation device of the radar transmitting baseband signals is improved, the PCB wiring complexity is reduced, and the cost of a radar simulation system is reduced.

Description

technical field [0001] The invention relates to the technical field of radar system simulation, in particular to a radar transmitting baseband signal generation device and method. Background technique [0002] As we all know, radar is widely used in military and civilian equipment, and the detection of radar performance also has very important guiding significance for the application of radar. For ordinary roadbed, vehicle-mounted and ship-borne radars, the identification of radar performance can be basically solved by testing the calibration parts in the field. However, for airborne radar, its real application environment is an altitude of several thousand meters. To achieve field calibration test, it must be realized through test flight. The cost, period, and resources of a test flight are often very huge, so it is impractical to completely rely on the method of test flight to detect the performance of airborne radar. [0003] Therefore, the industry usually uses simulat...
