Abstract :
Expediency of random ranging signals (RS) usage in weather radars (WR) intended for measuring reflectivity of meteorological formations (MF) is proved theoretically and experimentally. The results of synthesis of complex RS with super low side lobe level (SLL) of correlation function (CF) are given. For compression ratio 60 theoretically SLL -77 dB and experimentally -75 dB with losses less than 0.07 dB is received.
