Problems solved by technology

In the traditional method, the signal power attenuation is only related to the distance, and the orientation factor is not considered. It can only simulate the process of the radiation source tracking the target, but cannot simulate the process of the radiation source signal searching for the target, resulting in poor fidelity between the simulated radiation source signal and the real signal.

Embodiment Construction

[0022] like figure 1 Shown is a block diagram of the radar radiator signal simulation system with precise control of signal power. The specific workflow is as follows:

[0023] The radiation source signal generating unit receives the pattern and parameters of the radiation source signal, generates a baseband signal that meets the requirements and has a carrier frequency of 1.25GHz under the control of the system clock, and simultaneously generates a frequency code for controlling the variable frequency local oscillator frequency and a code for controlling the output amplitude of the broadband amplifier. Amplitude control signal, control output power amplifier modulation signal; the local oscillator and up-conversion circuit generate 6.75GHz-14.75GHz local oscillator signal under the control of frequency code, and the mixer up-converts the baseband signal to 8GHz-16GHz The radio frequency signal is sent to the broadband amplification and output control circuit after filtering o...

Description

technical field [0001] The invention belongs to electronic simulation technology, and relates to a radar radiation source signal simulation system with precise control of signal power, which can be programmed to generate real-time and rapid generation of typical mobile and missile-borne radar signals of combat opponents. Background technique [0002] In military training, real battlefield environment training is often required for radar warning equipment. Because of its characteristics of safety, convenience, flexibility, autonomy and high economic benefit, the radar signal hardware-in-the-loop electronic simulation system has become an indispensable means for troops in complex electromagnetic environments. The radar signal hardware-in-the-loop electronic simulation system mainly transmits analog signals to the radar warning equipment through the antenna. In actual use, due to the need for the layout of the simulation system, the simulation system is often fixed in one plac...
