Design of transmitter parameters for multi-beam staring photon detection

For detecting long-distance moving aerial targets, in order to solve the problem of low accumulation times and weak echo signal, this work proposes a multi-beam staring photon detection method. Firstly, the photon waveform expression of multi-beam staring photon detection is deduced. Then, the relationships between divergence angle, pulse width, single pulse energy, laser repetition frequency and photon probability distortion are discussed. Finally, the method of calculating the system transmitter parameters is obtained. The results show that when the detection target is the F22 flight with a speed of 400m/s at a distance of 10km, the number of beams is set to 40, the launch angle is set to 2mrad, the pulse width is set to 1ns, and the single pulse energy is set to 0.5μJ at the transmitting end. The research results provide a theoretical basis for the system design and realization of long-distance and fast-moving aerial targets.
