The solution to sidelobe suppression of the LFM and BC signal are discussed in details. For LFM signal, the method of employing Hammingweighting is demonstrated;
We propose a new design and numerically show that some optical properties of the optimized one are better than the optimized coupler with hamming function weighting.
