Abstract :
A new technique for detecting high-energy cosmic rays by using the front scattering of electromagnetic waves has been introduced recently. The reflected signals are captured by antennas and demodulated. The present work makes use of optimal filtering for detecting cosmic rays and removing the huge background noise. The detecting system achieves 98% of the detection efficiency for a false alarm probability as low as 1%.
