Dynamic model of particle impact noise detection

The space relay reliability influences the national defence system reliability seriously, and precaution and detection of relay remainder are the pivotal factor to enhance the relay reliability. Particle impact noise detection (PIND) is the American military criterion, but there is a lack of working mechanism research. From the point of view dynamics the paper establishes the collision mathematic models of relay remainder based on PIND, and lots of simulations are completed, and some results are obtained.
