高隔离度GPS干扰器设计与实现
Design and realization for high-isolation GPS jammer
摘要
Abstract
The research on Global Positioning System ( GPS) jamming and anti-jamming is of great significance for satellite commu-nication.A design and realization for high-isolation GPS jammer is put forward aimed at jamming original GPS signals. The generation of base code is based on Field-Programmable Gate Array( FPGA) hardware platform Virtex-5.Direct Digital Frequency Synthesis ( DDS) was completed under the control of an AD9956 chip drived by an STM8S105 microcontroller.With the help of di-viders, multipliers and unbalanced quadrature phase shift keying modulators, GPS jammer signals of L1 and L2 frequencies were derived.The L1 frequency and L2 frequency signals had characteristic of high-isolation and good performance on anti-noise.The pro-ject was testified by Integrated Software Environment simulation and advanced spectrum analyzer.关键词
