Broadband fast multifunctional signal generation assembly

Abstract

The invention belongs to the technical field of electromagnetic property application, and particularly relates to a broadband fast multifunctional signal generation assembly. The broadband fast multifunctional signal generation assembly comprises a frequency multiplication/power division module, a DDS (Direct Digital Synthesis) module and a frequency mixing module, wherein the frequency multiplication/power division module is used for performing frequency multiplication on a reference signal to obtain a clock signal and a local oscillator signal; the clock signal is transmitted to the DDS module; the local oscillator signal is transmitted to the frequency mixing module; an upper computer controls the DDS module to generate a baseband signal with variable bandwidth and wave form; the baseband signal is transmitted to the frequency mixing module; the frequency mixing module is used for performing frequency mixing on the local oscillator signal from the frequency multiplication/power division module and the baseband signal from the DDS module and then outputting. According to the broadband fast multifunctional signal generation assembly, the technical problem that the conventional signal generation equipment can only generate a signal of a specific form is solved. The assembly can output a time sequence control signal, a multifunctional frequency synthesizing function of a radar system can be realized after the assembly is connected with the radar system, and the measuring radar system design is obviously simplified.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic characteristics application, and in particular relates to a broadband fast multifunctional signal generation component. Background technique [0002] With the continuous development of target characteristic research, the demand for target characteristic measurement radar with multiple target characteristic measurement functions is becoming more and more urgent. The above-mentioned radar needs to have a variety of available signal forms, and can change the waveform signal at any time according to the work needs, so as to achieve a better evaluation of the measured target. [0003] In the existing technology, when designing target characteristics to measure multiple radar transmission signals, it is necessary to design various signals separately, resulting in technical problems such as multiple system interfaces, large volume, and difficult debugging.
