摘　　要：本文首先从认知雷达架构出发,基于雷达参数化的理念,提出雷达参数化波形的概念。雷达参数化即用一系列参数来表征雷达系统模型,参数化波形即雷达一系列控制参数的集合,对雷达系统的发射、接收过程进行参数控制。之后对参数化波形的具体内容进行介绍,并从频域、时域、空域三个方面对参数化波形进行详细设计,确定了其具体的参数形式。最后对一组参数化波形进行仿真验证。雷达的参数化波形可全面、有效地表征雷达的发射与接收过程中的系统各部分资源,通过改变其参数化波形参数可迅速改变雷达功能。对雷达参数化波形进行设计,可有效解决雷达在进行资源调度时控制何种参数的问题,有效表征雷达各部分资源。This article proposes the concept of radar parameterized waveform based on the cognitive radar architecture and the idea of radar parameterization.Radar parameterization refers to the use of a series of parameters to characterize a radar system model.The parameterized waveform is the collection of a series of control parameters of radar,which controls the transmission and reception process of the radar system.In addition,the specific content of the parameterized waveform is described,and the parameterized waveforms are designed in detail from three aspects,including frequency domain,time domain,and space domain.The specific parameter form is determined.Finally,a set of parameterized waveforms are simulated and verified.The parameterized waveforms of radar can comprehensively and effectively characterize the resources of each part of the radar system during the transmission and reception process.The radar function can be rapidly changed by changing parameters of the parameterized waveforms.The design of radar parameterized waveforms can effectively solve the parameter control problem during radar resource scheduling and effectively characterize the resources of each part of the radar.
