Monopulse laser static circumferential direction detection device and detection method

The invention discloses a single-pulse laser static circumferential direction detection device and method, the device comprises a pulse laser single-transmitting and single-receiving detection part and an optical static circumferential direction detection part, and the pulse laser single-transmitting and single-receiving detection part adopts a single pulse laser and a single laser four-quadrant sensor to sense a target; and the optical static circumferential detection part is used for realizing static beam expanding detection of a monopulse transmitted laser beam and circumferential acquisition of a target echo signal by utilizing a hollow total reflection mirror and an inverted conical reflection lens, and realizing monopulse laser static circumferential azimuth detection. Compared with the prior art, the single-pulse laser static circumferential detection is realized by matching the laser four-quadrant sensor with the inverted conical reflection lens, the target orientation is acquired only by adopting a s
