摘要:

在这项工作中,我们首先描述了一个框架的应用程序的强化学习(RL)控制的雷达系统,在拥挤的频谱设置。然后,我们通过讨论商业现货(COTS)硬件上进行的实验,比较了几种RL算法的实用性。每个RL技术的收敛性,雷达检测性能在拥挤的频谱环境中实现,并与非合作通信系统共享100 MHz频谱的能力进行评估。我们研究了策略迭代,它通过直接求解环境状态和雷达波形之间的随机映射来解决作为马尔可夫决策过程(MDP)的环境,以及深度RL技术,该技术利用一种形式的Q学习来近似雷达用于选择最佳动作的参数化函数。我们表明,RL技术是有益的,在一个感测和避免(SAA)计划,并讨论了条件下,每种方法是最有效的。

英文摘要:

In this work, we first describe a framework for the application of Reinforcement Learning (RL) control to a radar system that operates in a congested spectral setting. We then compare the utility of several RL algorithms through a discussion of experiments performed on Commercial off-the-shelf (COTS) hardware. Each RL technique is evaluated in terms of convergence, radar detection performance achieved in a congested spectral environment, and the ability to share 100MHz spectrum with an uncooperative communications system. We examine policy iteration, which solves an environment posed as a Markov Decision Process (MDP) by directly solving for a stochastic mapping between environmental states and radar waveforms, as well as Deep RL techniques, which utilize a form of Q-Learning to approximate a parameterized function that is used by the radar to select optimal actions. We show that RL techniques are beneficial over a Sense-and-Avoid (SAA) scheme and discuss the conditions under which each approach is most effective.
