This paper introduces the principles of Doppler radar signal processing method in the modulation . It provides the processing method for projectile tracer time, the burst time. rocket engine working time.
The structure of satellite antenna is increasingly faced to the requirement of enlargement now, which is contradict to the effective transportation capacity of the rocket, the solution is to use the reasonable space deployable structure on the satellite antenna.
In the field of modern control theory, it is a significant matter to study the signal estimation for stochastic systems with multiplicative noise, which is to obtain useful information from signals polluted by noises, for example, the state estimation of the dynamic system, the signal deconvolution estimation and the parameter recognition estimation, etc. It has important values of application in many fields, such as rocket control and guidance system, oil exploration, underwater object tracking, speech signal processing, communication engineering etc.
On the above-mentioned cognitive foundation, we try to study the electromagnetic reflectance of polar mesosphere in summer based on the theory of wave propagation in layered medium and under the precondition of ignoring the impact of anisotropy, The results of sounding rocket campaigns indicate that the electron density and the dust charge density of polar mesosphere in summer have layered structure.
All these research results are widely applied in military field such as aircraft, missiles and rockets but also in commercial areas such as mobile satellite communications, the broadcast satellite system, global positioning system (GPS), remote sensing.
The research work of the paper is with the servo system of measure radar, the author has participated in some previous transformations of the radar servo system and trouble hunting, has participated in and finished splendidly such scientific research task as rockets, satellite and airship, etc.
