Abstract

In this article, a qualitative work is carried out based on research of uniform PRF signal for phase noise analysis and accuracy parameter for RF sensor design. Presence of large clutter level in target return needs in-depth analysis of phase noise impact in clutter cancellation and importance of PRF selection in RF sensor processed SNR or accuracy. Detailed investigation of phase noise parameter in pulsed RF secnsor is examined out for target identification and tracking purpose. Critical aspects of phase noise in multiple PRF mode has been analyzed and Matlab simulations are carried out to support theoretical aspects of noise effects at particular offset. Impact of phase noise in clutter cancellation for uniform PRF waveform and multiple uniform PRF waveforms is evaluated in terms of SNR, sensor accuracy and allied limitations. Thus, outcomes can be utilized to unique analysis of PRF selection and phase noise together for RF sensor accuracy. Present work findings and results have been validated using simulation environment. This research outcomes offer great importance in design of highly accurate RF sensor.
