How to get enough shock environment information with limited system capacity is a key problem in space vehicle telemetry. In this paper, an airborne shock response spectra analyzer is developed based on FPGA which can real time calculate peak response spectra on board and then sending it to the ground station instead of the signal form three-axis accelerometer during the flight test. Flight test shows the analyzer can effectively compress the shock data and get enough shock environment information with limited system capacity. Moreover, the compression ratio of shock data can be flexibly adjusted according to the telemetry system capacity and real-time requirement of measurement, and some design parameters can be changed on-line. Therefore the analyzer has good applicability.
