Title:
RADAR SIGNAL WAVEFORM UNCERTAINTY TEST SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/170665
Kind Code:
A1
Abstract:
A radar signal waveform uncertainty test system, which comprises: during measurement, a radar excitation signal sent by a radar end machine is split into three paths via a power divider, the radar excitation signal on the first path produces a radar echo signal via a radar target simulator, and same is input into a reception terminal of the radar end machine; the radar excitation signal on the second path is delivered to a wide band collection, storage, and analysis device via a radio frequency cable, the wide band collection, storage, and analysis device measures the radar signal in real time, generates time, frequency, and modulation measurement data, and transmits same to a data analysis computer; and the radar excitation signal on the third path is radiated out by means of a radar antenna, an electronic reconnaissance device measures the power of a signal that arrived, generates power measurement data of the radar signal, and transmits same to the data analysis computer. Waveform uncertainty calculation software in the data analysis computer tabulates measured value change quantities in each dimension and calculates a waveform uncertainty of the radar signal. Test time for radar signal waveform uncertainty is short, and the present invention has a high degree of automation.
