为了减少无线电干扰对测试准确度的影响,长期以来测试需在屏蔽室中进行。无线电罗盘即为一例。空军推行原位检测,测试不能在屏蔽室中完成,其增益等难以标定。根据空军的要求,综合运用信号检测和估计理论以及自动检测技术,研制了抗干扰自动测试仪。试用表明,该仪器能在不使用屏蔽室条件下,在大噪声情况下,完成无线电罗盘增益的测试。
To reduce the impact of radio interference on test accuracy, long-term testing needs to be done in shielded rooms. A radio compass is an example. Air Force in situ testing, testing can not be completed in the shielded room, the gain is difficult to calibrate. According to the Air Force’s requirements, the comprehensive application of signal detection and estimation theory and automatic detection technology, developed anti-jamming automatic tester. Trial shows that the instrument can be used without the use of shielded room conditions, in the case of large noise to complete the radio compass gain test.
