Abstract

The invention discloses an interference signal modulation method for an injection-type interference semi-physical radar simulator, and the method comprises the steps that a software radar receives aninjection-type interference signal, modulates a radio-frequency interference signal of an interference machine according to the orientation and distance based on virtual station distribution information issued by a guide and adjustment system, and generates interference signal IQ data; the software radar receives the target empty situation issued by the pilot seat, and target and clutter IQ data generation is completed according to mathematical modeling; the software radar performs vector synthesis on the modulated interference signal IQ data, air condition IQ data and clutter IQ data; the synthesized data are radar baseband sampling signals and can be used for realizing radar signal processing and data processing algorithms.

Description

technical field [0001] The invention relates to a radar training emulator interference signal modulation method, in particular to an injection interference half-physical radar simulator interference signal modulation method, which belongs to the technical field of radar simulation trainers. Background technique [0002] The data generation of the radar training simulator includes two parts: interference signal generation, target and clutter signal generation. There are currently two situations. Situation 1: The interference signal is a fundamental frequency digital signal directly generated according to the model, which has a certain deviation from the real jammer signal, and cannot respond to radar anti-jamming operations, and cannot satisfy the closed-loop between jamming equipment and radar equipment in the actual radar electronic countermeasure process. confrontational scene. Case 2: The interference signal comes from the radio frequency signal of the jammer. After the...
