Analysis of Limitation Factors to MTI Improvement Factor

MTI is an effective measure for radar to detect targets from clutter environment. The working performance of MTI radar can be comprehensively reflected by improvement factor, and the factors influencing the system are concentrated on their limitations to the improvement factor. Basing on the MTI improvement factor, the limitations of interior and exterior factors such as equipment instabilities, internal fluctuations of clutter, antenna scanning and meteorologic clutter are considered comprehensively in this paper, and the stability of receiver system is given as an example to show the influence to the improvement factors of single and double delay-line cancellers.
