對於一個小區域性的突發事件(如森林大火、海上漏油……等)，空載雷達(如使用飛機、遙控飛機……等載具)及衛載雷達(使用衛星載具)會受到飛航管制和軌道的限制，無法作及時性與全時性的觀測，此時若有一地面影像雷達便可彌補這些限制。此外，地面影像雷達維護較空載、衛載雷達方便且維護費用更為低廉，因此在地窄人稠土地利用度高(如台灣)的區域，高靈活度的地面遙測系統是相當實用可行的。 本研究之主要目的即在於建立一地面影像雷達。而本文利用微波遙測、雷達原理等理論，對地面遙測影像雷達做一縝密的規劃。在本文中建立了一套影像雷達的建構程序，並利用此程序設計系統架構，制定元件規格，模擬系統運作情形。最後得到一地面遙測影像雷達的規格。 For small areas accidental events (such as bushfire, oil spill…etc.), airborne radar (such as uses airplane, remote control airplane…etc. as carrier) or satellite-borne radar (uses satellite as carrier) which will be restricted by air traffic control or limited orbit, is not able to do real-time, full time observation. Thus, if there is a ground-base remote sensing image radar system out there, the limitation can be resolved. Beside, the cost of maintenance of the ground-base image radar is less than others (airborne, satellite-borne), and the maintenance is easier. In a complex usefully terrain (as Taiwan), highly mobile ground-base remote sensing system is very practical. The major purpose of our research is to build a ground-base remote sensing image radar. This paper applies the remote sensing theory and radar principle to devote to the system design and simulation. In this paper, we have built a process to create a image radar. Using the process, we made our system structure, specified the system specification and simulated it. Finally, we got a specification of a ground-base remote sensing image radar.
