Single-photon laser active and passive imaging detection radar

The invention discloses a single-photon laser active and passive imaging detection radar which comprises a laser transmitting module, a laser ranging receiving module, a focal plane imaging detection receiving module, a time sequence control and ranging signal processing module, an active and passive imaging data separation module and a data processing module. The laser ranging receiving module receives a laser echo signal reflected by a target, and the time sequence control and signal processing module completes target distance calculation; the focal plane imaging detection receiving module completes active receiving and processing of echo signals in the mth measurement period based on n periodic pulse string gating signals sent by the time sequence control and signal processing module, and completes passive receiving and processing of n-1 measurement periods; the active and passive imaging data separation module realizes separation of active imaging detection data and passive imaging detection data; and the
