摘要:
 在综述汽车防撞雷达各种应用波形的基础上,提出了一种具有多重优点的波形设计-MFSK波形设计,并对MFSK波形设计的约束关系展开深入讨论.基于经过分析波形的信号原理,建立了多种FSK波形的信号处理模型,根据处理模型所给出的处理结果,同时结合性能参数的设计要求,提炼出了各种波形参数设计的约束关系,这是进行汽车防撞雷达系统设计的基础步骤.为了验证该理论模型和波形参数设计约束关系的有效性,分别对2-FSK、MFSK等信号波形等理论模型场景进行了Matlab实验仿真.仿真结果符合理论模型的预期,在不提升汽车防撞雷达信号处理成本的情况下,汽车防撞雷达系统运用MFSK信号能够提高数据的正确性,表明所提出的波形设计有效可行,具有较好的测距精度.
Abstract:
 On the basis of summarizing the various waveforms used in automobile anti-collision radar,the design of MFSK waveform with multiple advantages is proposed and the constrained relationship in the design of MFSK waveform is discussed deeply.The various FSK waveforms’ models of signal processing have been established by analyzing the waveform’s principle.Meanwhile according to the results of model processing,the constraints on waveform parameters have been extracted and purified combined with the requirements of performance parameter.In order to validate the design constraints between theoretical model and waveform parameter,the experimental simulations with Matlab have been conducted under the scenario of 2-FSK and MSK,and the results of which agree with the expectation of theoretical model.Therefore automobile anti-collision radar using MFSK is able to improve the accuracy of data,which proves waveforms is feasible and is of great accuracy without increasing signal process costs.
