| Abstract: | Pulse compression technique avoids the transmission
of a signal having small pulse width and high peak power
for better range resolution by transmitting phase or frequency
modulated large pulse width signal having comparatively low
peak power signal. This paper demonstrates an application of non
dominated sorting genetic algorithm-II (NSGA-II), a multiobjective
algorithm, to generate biphase pulse compression codes from
length 49 to 59. But the aperiodic autocorrelation function(ACF)
of the phase coded signals contains range sidelobes which act
as self clutter in radar target detection. The efficiency of these
codes depends upon the energy content in the range sidelobes
of their autocorrelation functions. Peak sidelobe level (PSL) and
integrated side lobe level (ISL) are the two performance measures
for pulse compression codes. A code is chosen for an application
if the ISL and PSL value is within tolerable limits. In this work
PSL and ISL are chosen as the objective fun... |
