Abstract
In this paper, low rang time side lobes for pulse compression in weather radar can be achieved by an integrated scheme using non-linear FM, tapering transmission waveform, mismatched windowed filter. The simulation process to search optimum realization scheme is presented to make sure least enlargement of main lobe pulse-width while mitigating energy of side lobes. The result of simulation indicates that side lobes can be less than 60 dB while main lobe width will not surpass 0.66 mus. In the end, the implement of the scheme is designed for realization.
