Abstract: The Standard Radiation Environment Monitor (SREM) belongs to a second generation of instruments in a program established by the European Research and Technology Centre (ESTEC) of the European Space Agency (ESA) to provide minimum intrusive particle radiation detectors on ESA spacecrafts for space weather applications. SREM detects high-energy electrons and protons and bins the measurements in overlapping energy channels. In order to estimate the particle fluxes associated with Solar Particle Events (SPEs), a method based on the Singular Value Decomposition (SVD) analysis was developed. This method does not require any assumption on the spectral form of the particle fluxes and includes proper schemes treating issues related to several characteristic properties of the detector. As an example, we present results associated to the January 20, 2005 SPE.
