Description
RADAR system can be used in low altitude for surveillance, terrain information acquisition and other purposes in commercial or military fields. One big problem with the RADAR system is the large backscattering signals from target or clutter. These will make the receiver saturated or degenerated. Sensitivity Time Control is one of the methods to overcome this problem. The STC also has other effect such as rejection of the clutter because RADAR normally distinguish targets depending on whether the received signal’s value is above the specific threshold value or not, and STC can make clutter signal smaller than the threshold value. Therefore system designer should choose proper STC performance according to the clutter. This paper focuses on design of optimized STC performance for RADAR which is used for gathering terrain information within the RADAR detection range such as mountains, hills, buildings or man-made structures. In this case, ground is the most interesting clutter. Therefore STC should be designed from received ground power according to the range. This STC is also applied in actual non-coherent RADAR system to measure the surrounding terrain to compare simulation and actual performance.
