Introduction

A monostatic radar is a configuration in which a waveform is both transmitted and received from the same antenna. This is beneficial as the receiver knows the transmitted signal and does not have to be synchronized. One issue with this configuration, however, is that these systems are more susceptible to jamming. It is hypothesized that the implementation of a chaotic system in radar could help avoid this problem. Previous research has found the use of a random Gaussian waveform efficient in avoiding a jammer [1].  Because a chaotic system has a similar random property, it is hypothesized that a chaotic system could avoid jamming as well. Additionally, research has found that the implementation of a chaotic system in a bistatic radar to have high range resolution imaging capabilities [2]. This is because of a chaotic waveform’s resemblance to noise and that a chaotic system has a high bandwidth. This allows for a lower range resolution as the higher a signal’s bandwidth is, the less distance is required between two objects for a radar to distinguish between both objects. In this paper, multiple chaotic systems, including the previously analyzed Lorenz system, were examined to see if they have high range resolution capabilities in a monostatic radar system. The systems that were tested include Lorenz, ACT, Rossler, and Chen.
