The invention discloses a high-dynamic high-sensitivity broadband receiver with self-adaptive interference suppression. The broadband receiver includes an FPGA digital processing module, a main channel receiving module and at least one interference scanning receiving module; the FPGA digital processing module controls the interference scanning receiving module to perform rapid scanning and obtain a single or a plurality of interference frequency points having the maximum influence on receiving performance, and tunes a suppression frequency band of the main channel receiving module so as to enable the main channel receiving module to maximally suppress dynamically varying out-of-band interference; the main channel receiving module tunes a passband and poles according to a control signal sent by the FPGA digital processing module; and the interference scanning receiving module is used for performing scanning in a full frequency band, locking the strongest interference, and providing interference frequency points and amplitude for the FPGA digital processing module. The high-dynamic high-sensitivity broadband receiver with self-adaptive interference suppression can dynamically track interference and accurately suppress interference, thereby greatly improving receiver performance under dynamic interference.
