- Abstract
- This paper is proposed the coupled line to discriminate the RF channel failure for active phased array. It is important to check the operational status of numerous channels in active phased array. The coupled line structure with slot was used to obtain the required signal level to check the channel status. The measured coupling level of coupled line shows about - 30 -50 dB and it was enough level to check the channel failure of the radar system.
