Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0055] The specific steps of a multi-target signal synthesis method without breakpoints are as follows: figure 1 As shown, firstly, according to the characteristics of the pulse signal, a single signal is divided into two parts: signal sample point (pulse width part) and idle sample point (remaining part after removing the pulse width in one pulse period). Secondly, store signal samples in RAM, generate multi-target signal files, and generate signal c...

Abstract

The invention relates to the field of radar target signal generation and simulation. The purpose is to provide a non-breakpoint multi-target signal synthesis method. First, the user inputs signal parameters through the interface provided by the signal generation software; then calculates the signal memory utilization, calculates the size of the memory space occupied by the signal, and adjusts the pulse signal according to the accuracy requirements of the multi-target signal. PRI, arrange the adjusted multi-target signal timing and perform gain calculation to obtain the multi-target signal envelope information; then perform intra-pulse information processing, add signal intra-pulse information, and form a multi-target waveform file; finally generate a multi-target waveform through arbitrary waveforms The multi-target waveform file is called by the converter to generate a multi-target analog signal. The multi-object signal synthesized by the method of the invention has the advantages of high utilization rate of hardware resources and high precision of the multi-object signal.

Description

technical field [0001] The invention relates to the field of radar target signal generation and simulation, in particular to a multi-target signal synthesis method without breakpoints. Background technique [0002] Modern radar systems are comprehensive and sophisticated, capable of simultaneous scanning, tracking, identification, and target strike operations. When developing and testing radar systems, it is usually necessary to use a suitable target simulator for testing. Limited by hardware conditions and simulation methods, most of the currently used target simulators are only for certain types of specific targets, and the timeliness of the simulator output targets and the accuracy of each target will be limited. Contents of the invention [0003] In view of this, the present invention provides a non-breakpoint multi-object signal synthesis method, which has the advantages of high hardware resource utilization and high multi-object signal accuracy. [0004] In order t...
