Millimeter-wave high-power radar signal simulator and simulation method

Abstract

The invention provides a millimeter-wave high-power radar signal simulator and a simulation method. The simulator comprises a millimeter-wave radar signal simulator host, a millimeter-wave radar signal simulator power amplifier, a high-gain antenna and a loudspeaker antenna group; the millimeter-wave radar signal simulator host includes a modulation source module, a locked-phase source module, a mixing and filtering module, an agile source module, an amplitude stabilization module, and a power division module; signals output by the modulation source module and signals outputted by the locked-phase source module are inputted into the mixing and filtering module so as to be subjected to mixing and filtering, and obtain signals and signals outputted by the agile source module pass through theamplitude stabilization module and are divided into two paths of output; one path of the output enters the millimeter-wave radar signal simulator power amplifier so as to be amplified, the amplifiedsignals are converted into single-target output through the high-gain antenna; and the other path of the output enters the power division module and is converted into multi-target output through the loudspeaker antenna group. The simulator of the invention has the advantages of powerful simulation function, wide band (32-40 GHz), large output power (up to 10 W), convenient operation and use, highuniversality, high frequency index and the like, and satisfies the function and performance testing requirements of a millimeter-wave radar warning receiver and also meets the simulation and testing requirements of a millimeter-wave electronic reconnaissance receiver.

AI Technical Summary

Problems solved by technology

At present, the radar signal simulator is mainly based on a single function, or the system is single, or the frequency band is not enough, or the channel is single, and it cannot realize long-distance space radiation. The use environment is limited, and the working high frequency bandwidth of the existing radar simulator is basically in the 2-3GHz, and cannot work in the millimeter-wave frequency range of 32-40GHz. For example, patent application CN201510882404.2 discloses a multi-system radar signal simulator. Although it achieves a wider frequency range, that is, 0.7-18GHz, its The frequency is very low, the maximum is only 18GHz, it cannot be used in the high frequency band range, and its use environment is also greatly restricted, and only long-distance space radiation can be realized
