The invention discloses a method for implementing pull-off interference on a seeker radar, and belongs to the technical field of radar signal interference. The method comprises the following steps: receiving a radar signal of a seeker radar with a distance gate, processing a radar pulse, and establishing an interference strategy; obtaining external environment interference factors, and carrying out sampling optimization on the radar signals; confirming a pull-off type, and confirming a relationship with a target; establishing different pull-off laws for different pull-off types, and implementing pull-off interference on the radar. According to the invention, various pull-off laws can be established, an external complex electromagnetic environment is considered, the signal processing precision is improved, a multi-cycle crossing mode is provided, and the problem that pull-off interference is applied to the radar when the inherent time delay of the system exceeds a radar distance detection wave door is solved. By means of the method, the false target position can be provided in the radar reconnaissance process, real target position-speed information can be effectively hidden, the practical significance is achieved, and national defense safety in China is protected.
Description
technical field [0001] The invention relates to the technical field of radar signal interference, in particular to a method for implementing towing type interference on a seeker radar. Background technique [0002] Implementing tow-type interference on the seeker radar is a self-defense technology. The jammer emits a false echo pulse with an incremental delay from the radar echo pulse. Since the radar determines the target distance by measuring the arrival time of the echo pulse , so this technology makes the target distance measured by the radar different from the real target distance, and its essence is to delay the accurate distance information of the radar. [0003] Existing towing interference includes speed towing, distance towing, and combined speed and distance towing, but the law of towing is relatively simple, and the signal processing is relatively simple. It is impossible to adopt different processing methods for different devices under test, and cannot satisfy ...
