Description

technical field [0001] The invention relates to an X-ray generating device, in particular to a highly stable arbitrary waveform X-ray generating device and a generating method, which is an important experimental device suitable for X-ray detector performance testing and navigation algorithm verification of X-ray pulsar navigation. It is also an important test device suitable for closed-loop testing of X-ray pulsar navigation payloads and their navigation algorithms. Background technique [0002] In order to carry out research on X-ray pulsar navigation technology, it is necessary to simulate the physical parameters of X-ray pulsars (pulse profile, stability, energy spectrum, etc.) in the laboratory. Based on the existing database of candidate pulsars, a full-physical simulation is carried out, mainly simulating the relative spatial coordinates of pulsars, X-ray energy spectrum range, pulse profile distribution, pulse profile stability and other indicators.

Problems solved by technology

This scheme is simple and easy to implement, but it has the following three disadvantages: one is that the speed stability of the DC motor is only 10 -4 , the stability of the output pulse is very poor; the second is that it is difficult to realize the analog output of any pulse; the third is that the operation is very troublesome. To change the period and shape of the pulse, the metal blade must be replaced every time

Based on the above limitations, it is difficult to achieve physical simulation of X-ray pulsars

At the same time, the existing simulation generation systems for pulsar signal sources, such as Chinese patents "X-ray Pulsar Navigation Embedded Simulation System Based on Semiconductor Laser" (200910023357.0), "A Pulsar Signal Simulator" (200910023383.3), "Multiple pulsar signal simulator" (200910023707.3), etc., did not realize the pulsar X-ray simulation signal with an energy spectrum in the range of 1-20keV
