Paper Abstract

This paper addresses impact of frequency source noise in terahertz (THz) moving objection detection systems. Oscillator noise deserves special attention in terahertz (THz) moving objection detection systems since phase jitter in high-power THz frequency source is relatively serious. Such phase jitter (noise) will lead to a few serious problems and seriously affect performance of THz moving object detection systems. In this paper, quantitative estimates of impact of frequency source noise in THz moving target detection systems are derived analytically and requirement for coherent accumulated time limited by frequency source phase noise is deduced based on the second-order statistics characteristic of the oscillator phase noise. This research results could further consummate THz theory system and provide theory basis for the system design.
