Abstract

The invention discloses a fuze body object simulation method. The method specifically comprises: performing sampling on radar emission signals, obtaining digital signals, and distributing the digital signals to a plurality of digital signal channels; in each digital signal channel, according to the speed of the scattering points and the delay amount of each digital signal channel, modulating the digital signals of the digital signal channels; performing digit-simulation conversion on the modulated digital signals for obtaining the output signals of the digital signal channels; and unifying the phases of the output signals of the plurality of the digital channels, synthesizing the output signal obtaining synthesis signals of the digital channels at an intermediate frequency vector, and according to the synthesis signals, obtaining high-frequency synthesis signals and performing space radio frequency radiation. By the method and system, the problem can be solved that a point target simulator cannot perform real simulation on a fuze object, the fuze body object can be simulated in a more real manner, the phase continuity can be maintained when the signals are delayed, the actual effects of fuze simulation are achieved, and the simulation degree and precision of a radar simulation system are improved.

Description

technical field [0001] The invention relates to the field of radar radio frequency simulation and is applied to a radar simulation system, in particular to a fuze body target simulation method and system. Background technique [0002] Radar signal simulator is the combination of simulation technology and radar technology. It evaluates the technical and tactical indicators of the tested radar by simulating the radar echo signal, and assists in testing the power and accuracy of the radar. There have been a lot of reports on research in this field abroad: KOR Electronics of the United States has developed a digital radar environment simulator (Digital Radar Environment Simulator), and HP has produced an X-band radar moving target based on a parallel FASS (Frequency Agile Signal Simulator). Signal Simulator. Domestic research reports on radar signal simulators have appeared successively since the 1990s: Beihang University and the 601 Institute of the Ministry of Aerospace Scie...
