ABSTRACT

This thesis presents the analysis and computer simulation of continuous wave radar detection system for moving targets. In the past, radio detection has been used as an integral part of complicated applications like reconnaissance mission, navigation, weather, air-traffic management, missile targeting and defense. Analysis of measuring systems for such applications needs the representation of radar operation and performance within the context of the system. The impact of measuring these systems needs to be evaluated and quantified. Signal processing in radar systems was carried out using MATLAB with linear frequency modulated continuous waveform(LFMCW) to obtain the target distance and relative speed for moving targets. A model for detection of continuous wave radar was developed to generate different frequencies at different distances. The results obtained were able to detect normal frequency whenever a change in radar distance occurred within the moving targets environment. The analysis of delay time and modulation frequency reviewed the degree to which delay time contributes to the detection of targets. For fast moving targets, a higher delay time was needed while for slow moving targets, a lower delay time was needed. The analysis of radar distance and modulation frequency confirmed the need to increase our modulation frequency to detect fast moving targets while there is need to reduce the modulation frequency to detect slow moving targets. Analysis of blind speed and range affirmed that, moving targets in an irregular pattern can be detected by the developed model. Hence, the developed model was not limited to targets moving in a straight line but for targets moving in any direction.
