Abstract:	本研究將探討中壢地區較長週期的行星波及潮汐與雷達所偵測到散塊E回波的關連性，中壢雷達所觀測到的3公尺場列不規則體回波，由於執行不同實驗及不同季節，連續偵測到散塊E回波最長時間大約只有一周，不容易做較長時間的討論，但利用國家通訊傳播電離層觀測站(NCC)的散塊E臨界頻率foEs資料，可以討論全日半日或8小時週期的變化，做為電離層背景週期變化的參考。雷達觀測的回波經常是片斷，本研究將利用最近取得一筆連續20天，加上其他三筆7天的雷達回波，探討較長週期現象及可能的產生機制。 The occurrence relation of sporadic E (Es) that detected by Chung-Li VHF radar to planetary and tidal waves will be investigated in this proposal. We will use the critical frequency of Es layer (foEs), provided from The National Communications Commission (NCC), as the background periodic reference. One set include 20 days consecutive Es signals received this summer and another 3 sets signals will plan to analyze in this proposal.
