Abstract

Advances in unmanned aerial vehicle technology have increased its use in a wide variety of fields. One of the advantages of drones is their ability to perform remote inspection and sensing by placing various types of sensors on them. From this perspective, UAV-based ground-penetrating radar systems are of particular importance. One of the key indicators to ensure target detection in radars and spectral integrity in communication systems is phase noise. This index is rapidly becoming the most critical factor that is considered in radar and communication systems. Phase noise is the frequency and phase instability of a signal source, oscillator or clock, which is an undesirable and unavoidable factor and has adverse effects on the performance of radar systems. The purpose of this article is to investigate the effect of phase noise in the airborne ground penetrating radar system. For this purpose, a continuous wave radar system with frequency modulation has been considered for exploring a region of the three-layered earth. The three-layer model of the earth is simulated in gprMax software, and the impact response of this model is extracted and stored after the simulation. This output file was analyzed in MATLAB software in order to apply processing of frequency modulated continuous wave radar system and finally two-dimensional image was extracted. The working frequency range of the radar system was considered from 100 MHz to 3 GHz. In order to investigate the effect of phase noise in this two-dimensional image, phase noise has been added to the local oscillator signal in the receiver. By examining the results, it is clear that in the presence of phase noise, the targets and the junction of the layers in the output image are blurred and cannot be recognized correctly.
