Abstract

The invention discloses a hyper parallel processing automatic generation type real-time multi-target echo simulation method for a phased array radar. The hyper parallel processing automatic generationtype real-time multi-target echo simulation method comprises the steps of: establishing motion models of complex moving targets; generating target baseband echoes and noise according to system parameters, and calculating target information of all the targets by utilizing the target motion models according to target parameters; for a certain target, adding distance information and speed information of the target into a target baseband echo signal to construct single-channel data of the target; adding azimuth information of the target into the single-channel data to construct multi-channel echodata of the target, and adding the multi-channel echo data with the noise to construct phased array radar echo data of the target; and traversing all the targets, and performing linear accumulation on the echo data of different targets to construct final multi-target phased array radar echo data. The hyper parallel processing automatic generation type real-time multi-target echo simulation methodis used for evaluating the signal processing performance of a radar system for multiple targets, and can be used for improving the comprehensiveness of performance evaluation of the radar system.

technical field [0001] The invention belongs to the field of echo simulation in radar systems, and relates to a real-time multi-target echo simulation method of a phased array radar of a super-parallel self-generated type. Background technique [0002] In the R&D process of radar systems, performance testing and algorithm verification are indispensable and important links. Usually, it is necessary to verify the effectiveness and stability of signal processing algorithms by simulating echoes. At present, according to the generation method of the echo signal, the radar echo simulation can be divided into two types: one is the storage and playback type, and the other is the independent generation type. The storage and playback type generally solidifies the radar echo data obtained in advance in the memory. When simulating the echo, the echo is read out according to a certain timing control for subsequent signal processing. The autonomous generation method automatically generat...
