The invention discloses an ignition and detonation combustor by utilizing shock wave focusing and an ignition and detonation method thereof, and belongs to the technical field of engines. According tothe combustor, a primary shock wave focusing chamber performs high-frequency reciprocating translational motion along with a dynamic concave cavity and is periodically connected and disconnected witha gas collecting flow guide cavity, generated shock waves are reflected in the concave cavity, focused to form a local high temperature and directly ignites combustible mixture to crack and oxidize macromolecular fuel in a high-pressure area, so that a large amount of easy-to-detonated activating groups and micromolecular gas are generated; and a secondary shock wave focusing chamber is reverselyarranged relative to the primary shock wave focusing chamber, the reflected shock waves in the primary shock wave focusing chamber are reflected again in the secondary shock wave focusing chamber, focused to form a three-wave structure to form a local high temperature and directly detonates detonation waves in the high-pressure area. The invention further provides an ignition and detonation method. According to the method, two-time shock wave focusing is adopted for ignition, so that the stability of the working process is effectively improved, and compared with a traditional shock wave focusing ignition mode, the method effectively enhances the high-frequency cyclic detonation characteristic.
