Abstract
Detection sensitivity is an important indicator of the X-ray pulsar detector. In order to achieve the accuratesensitivity of the detector, a new method of calculate detection sensitivity is proposed calculation. Combining with the characteristics of X-ray pulsar radiation spectrum and detector spectral,classic pulse accumulation model is corrected.A new signal to noise ratio (SNR) calculation formula is deduced by using the new pulse accumulation model.Constructing a new variable Z, which has close relationship with SNR. Through setting the SNR, the analysis and simulation verification for detection sensitivity and confidence level can be made.Simulation verification shows that the monte carlo simulation result is consistent with the theoretical results, and the maximum deviation is only 5%, which is far less than the deviation caused by the space environmentdisturbance.
