对于选择“直接耦合式陀螺稳定”位标器的方案,探测器以及有关电子线路将受到主要来自位标器的陀螺电机和电磁力矩器的较强电噪声和磁噪声的干扰,致使系统噪声成百倍增加。低噪声锑化铟探测器位于位标器中的低频电磁辐射源附近。所受到的磁噪声干扰主要是由于器件的两根引线造成的,采取缩短探测器引线间距,采用双绞线以减小引线回路面积,可使噪声减小约十倍。尖峰噪声是位标器中电噪声对探测器干扰的另一种形式,抑制尖峰噪声的方法是减小干扰源与探测器之间的电场耦合,这种方法可使噪声降低约十五倍,基本消除了尖峰噪声干扰。
For scenarios where the “Direct Coupling Gyro Stabilizer” is selected, the detector and associated electronics will be interfered by the strong electrical and magnetic noise of the gyro motor and the electromagnetic torque primarily from the scaler, causing the system The noise increases a hundredfold. The low-noise indium antimonide detector is located near the source of low-frequency electromagnetic radiation in the marker. The magnetic noise interference is mainly caused by the two lead wires of the device. By shortening the detector lead spacing and using twisted pair wires to reduce the lead loop area, the noise can be reduced by about ten times. Spike noise is another form of electrical noise in the marker that interferes with the detector. The method of suppressing spike noise is to reduce the electric field coupling between the interferer and the detector. This method can reduce the noise about fifteen times, The basic elimination of spikes and noise interference.
