Embodiment Construction
[0033] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.
[0034] Such as figure 1 The radar active signal source shown is composed of a down-conversion unit, an intermediate frequency signal processing unit, a frequency synthesis unit, and an up-conversion unit. All units are placed in a non-standard 4U CPCI chassis. Down-conversion unit: Receives the radio frequency signal emitted by the radar, and performs down-conversion and power conversion on the radio frequency signal, down-converts the radio frequency signal to the working frequency range of the intermediate frequency signal processing unit, and outputs the converted signal to the intermediate frequency signal processing unit. Intermediate frequency signal processing unit: the core component used to generate various target, interference and radiation source t...

The invention discloses a radar active signal source. A frequency synthesizer unit is used for generating a down-conversion local oscillator signal, an up-conversion local oscillator signal and a reference clock signal; a down-conversion unit is used for receiving the radio-frequency signal and the down-conversion local oscillator signal output by the frequency synthesizer unit, performing down-conversion and power conversion on the radio-frequency signal, and outputting an intermediate-frequency signal to the intermediate-frequency signal processing unit; an intermediate frequency signal processing unit is used for receiving an intermediate frequency signal output by the down-conversion unit and a reference clock signal output by the frequency synthesizer unit, performing digital modulation on the signals and outputting the modulated signals to the up-conversion unit; and an up-conversion unit is used for receiving the signal output by the intermediate frequency signal processing unit and the up-conversion local oscillation signal output by the frequency synthesizer unit, performing frequency mixing on the signal, performing up-conversion to an X / Ku wave band and a Ka wave band, and performing signal output according to a required amplitude. According to the invention, coherent and non-coherent radar signal simulation functions of multi-band and complex moving target signals are integrated.
Description
technical field [0001] The invention relates to the technical field of radar signal sources, in particular to a radar active signal source. Background technique [0002] As an important device for military avionics detection and positioning, radar plays an important role in reconnaissance, positioning, tracking, and guiding operations in the military. The current radar has many technical systems and working modes, and the movement patterns of the detected target signals are complex and changeable. It can identify various interference signals and can work across bands in a complex electromagnetic environment. Based on the above new radar technical requirements, traditional radar signal sources in the laboratory environment can no longer completely simulate radar combat scenarios and evaluate radar combat capabilities. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies in the prior art and provide...
