Abstract:

This study presents the design and implementation of a high-resolution radar extended target simulation system for simulating extended target echoes in high-resolution radar. The study establishes target echo models for one-dimensional distance targets, two-dimensional surface targets, and three-dimensional volume targets. The key technologies used to achieve the design and implementation of the high-resolution radar extended target simulation system include wideband RF receiver technology, large instantaneous bandwidth baseband echo signal generation technology, target RCS(Radar Cross Section) data acquisition and modulation technology, and wideband agile frequency synthesizer. The system is used to conduct RF simulation and two-dimensional imaging processing of a typical fighter jet target, and the results are compared with the simulation results obtained using RadBase simulation software to verify the effectiveness of the system. The validation results indicate that the RF simulation and two-dimensional imaging processing results of the system are consistent with the simulation results obtained using the RadBase software.

Key words: extended target, echo model, one-dimensional range image, two-dimensional surface target, three-dimensional volume target, high resolution force radar
