| Abstract: | Multi--target location is the key technology that is needed to be resolved instantly in our country new heavy anti--ship and anti--sub-marine torpedo. To realize the design of analog signal generator used in water--tank test system of multi--target location, this paper proposes a method of using LabVIEW that is a kind of graphical program language to program on PCI2007C digital to analog card and multi--channel signal processing card. This paper describes program flow of PCI2007C card and the function ultimately realized and the method of avoiding signal distortion in detail. The test indicates that the signal generator can process all kinds of target echo exactly, that is multi--channel narrowhand or broadband signal differing in time delay, frequency and amplitude. |
