A study of quasi-continuous waveform (QCW) and its performance in detection is presented taking into consideration eclipsing loss and free space decay. Genetic algorithm is then used to optimise the waveform and lower the dynamic range of the matched filtering output. The resulting waveform with high duty cycle and minimal loss at maximal range maintains good detection performance along the whole operating range of the radar.
