Novel unequal spacing multi-pulses technology to enhance SNR for pulse laser radar

A novel multi-pulses technology with unequal space to enhance SNR of pulse laser radar is proposed in this letter. Traditional multi-pulses technology employing equal spaces multi-pulses always leads to many outputs once the time window has pulses no matter the number of pulses, which is difficult to identify which one is the main pulse we want to get. Thus we propose a method using unequal spaces multi-pulses to improve the poor performance of the equal space multi-pulses technology, which means our method will get only one pulse output when the time window has pulses input. Both simulation and experimental results show the validity of our algorithm.
