| 摘 要： | 讨论C/A码与P(Y)码重复周期的不同对各自抗干扰性能的影响。探讨涉及P(Y)码接收机抗干扰性能的认定问题。分析表明:多数情况下P(Y)码接收机具有比C/A码接收机远高出10dB的抗干扰性能;转发式干扰对P(Y)码接收机很难达到欺骗效果。

| Abstract: | The difference in anti-jamming performance between GPS C/A and P(Y)-code due to code length difference is analyzed.Analysis with several jamming waveforms indicates that the difference in anti-jamming performance between GPS C/A-code receiver and P(Y)-code receiver is much more than 10dB in many circumstances.The repeater jamming is not of advantage for interfering with GPS P(Y)-code receiver. |
