ABSTRAK :
Radar system is urgently needed in all airports or military bases to detect
aircraft presence and position, either for commercial or military aircrafts. One of
the troubles witch always accur in radar is noises, either internally noises such as
thermal noise, shot noise and transit time noise, or externally noises such as
atmospheric noise, extraterrestrial noise and man-made noise. In this research
hast simulated the presentation and diplay of radar parameters by using
calculation of SNR (Signal to Noise Ratio) formula. Parameters used in this
simulation were Power, Gain, SNR Analysis from FM-CW radar and the resulted
power calculation data toward the determined distances, the influence of the
noises being discussed in this research was limited to the strengthening of radar
antennae and did not discuss the angle of target objects. Simulation in this
research used a MATLAB version 2008 software. This research resulted final data
in the forms of figures and displays of SNR graphs to power, SNR graphs to gain,
SNR graphs to FM-CW radar, and power graphs to range. Those graphic displays
obtained values for the target covering distance range by entering the data from
power and gain; meanwhile, result from the calculation of power and distance of
a target had been determined. Further, it could also be known the data from SNR
results within the values of determined radar parameters.
