Embodiment

[0056] The broadband target emulator verification platform of this embodiment is as figure 1 As shown, it specifically includes a signal generation module, a data acquisition module, and a data analysis module. Each module and its method are introduced separately below.

[0057] 1. Signal generation module and method

[0058] The signal generation module is a wideband radar signal source based on DDS technology. The signal source needs to generate the transmit signal, the local oscillator signal and the frame synchronization signal. In order to save hardware resources, the signal source only needs to design the DDS parameters according to the frequency of the local oscillator signal. The transmit signal is obtained by multiplying the simple pulse of equal period and the local oscillator signal. , while the frame sync signal is an I / O signal. The implementation of the signal source is to build an algorithm based on the SystemGenerator platform, use the DDS module to generate t...

Description

technical field [0001] The invention relates to a verification platform and a verification method, belonging to the field of radar measurement and control, in particular to a wide-band target simulator verification platform and a verification method. Background technique [0002] The target simulator is a test platform that generates target echo signals and interference signals required for radar testing based on the target model and motion attitude simulation. The target simulator verification platform is to verify whether the test signals generated by the simulator meet the requirements. [0003] As the range of the radar to be tested becomes wider and the test accuracy requirements are higher and higher, the target simulator is also developing in the direction of multi-band, multi-mode, and large bandwidth. At present, the most extensive research on simulator technology is ultra-wideband, The simulation of high-resolution radar echo signals and step-frequency radar signa...
