摘要/Abstract

摘要：

在自适应交互多模型的框架下，提出了一种雷达发射波形选择方法．将常速模型和“当前”统计模型应用到交互多模型算法中，得到自适应交互多模型跟踪算法．从信息论的角度出发，对误差椭圆正交法进行了推导，并给出其控制论角度的等价形式．根据这种等价形式，该方法存在无法调节距离和速度跟踪误差权重的问题．针对这个问题，结合自适应交互多模型跟踪算法，提出了基于最小均方误差准则的自适应雷达发射波形选择方法．

Abstract:

Within an adaptive interacting multiple model (IMM) framework, an approach to selecting the transmitted waveform of radar is proposed. The adaptive IMM algorithm is attained when the constant-velocity (CV) model and the current statistical model are applied to the IMM filter. Firstly, the error ellipse orthogonal method is derived from information theory, and an equivalent form is given in terms of control theory. According to the equivalent form, the range and velocity tracking error can not be adjusted effectively using the error ellipse orthogonal method. To solve this problem, an adaptive transmitted waveform selection approach is proposed based on the minimum mean-squared error, combining with the adaptive IMM algorithm. Simulations show that the proposed algorithm is feasible and effective.

Key words: cognitive tracking, adaptive tracking, interacting multiple model, waveform selection, ambiguity function, fractional Fourier transform
