This work addresses the development of algorithms for online automatic detection of meteors using radar technique. In time-domain, the optimal filtering technique is applied. In frequencydomain, two possibilities are being studied using Short-time Fast Fourier Transform: narrowband demodulation and cumulative power spectrum analysis. The filter detecting system using the power spectrum analysis achieves 94.2% efficiency for a false alarm rate of 6.7% over 1,500 seconds of data, which could avoid to record 3.45 GB of noise every 24 hours.
