| Abstract: | This paper studies the range sidelobe suppression techniques for long-quadriphase coded signals by applying digital processing in frequency domain. By analyzing the spectrum characteristics of Taylor quadriphase coded signals, a design method in frequency domain for sidelobe suppression filters (5SF), which is suited for various code lengths is presented. As an example, computer simulations and experiment results of 127-bit Taylor quadriphase coded signals processed by the SSF are also given. When f_d=0, R?VIS are achieved respectively to 51dB and 43dB for simulations and experiments. These results show that Taylor quadriphase coded signal 5SF designed by this method can be applied in modern radar systems. |
