Abstract

The invention belongs to the technical field of radar test equipment design, and particularly relates to radar test equipment, which comprises a general storage module used for storing radar record data including target echo information, interference information, clutter signals, SAR information and other radar radiation information, a baseband signal processing module performing digital up-conversion and playback based on the radar record data to generate a digital intermediate frequency playback signal, a DAC module used for carrying out digital-to-analog conversion on the digital intermediate frequency playback signal to generate an analog intermediate frequency playback signal, a broadband up-conversion module used for carrying out up-conversion on the analog intermediate frequency playback signal to generate a radio frequency playback signal, and two broadband transmitting channels used for amplifying and outputting the radio frequency playback signal, so that a target echo signal, an interference signal, a clutter signal, an SAR signal and other radar radiation signals based on radar record data can be simulated.

Description

technical field [0001] The application belongs to the technical field of radar test equipment design, and in particular relates to a radar test equipment. Background technique [0002] Radar testing equipment is used for radar debugging, performance testing, and countermeasure testing. Existing radar testing equipment cannot simultaneously simulate radar target echo signals, radar interference signals, radar clutter signals, and other radar radiation signals in different frequency bands. It satisfies the general testing requirements of radar very well. [0003] In view of the existence of above-mentioned technical defect, propose this application. [0004] It should be noted that the disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of the present invention, and it does not necessarily belong to the prior art of this patent application. When the filing date has been published, the abo...
