In this paper, a modeling and calculation method for the Radar Cross Section ( RCS) of complicated satellite targets is introduced, and the method is applied to the calculation and simulation of cube and cylinder with perfect conductor characteristic. Finally, the calculation instance of satellite target RCS is realized, and the result is contrasted to the satellite with metal material. The conclusion is that the method adopted in the paper can simulate the message of dielectric surface and effectively and fleetly calculate the RCS of multi-layer material for complicated targets.

A method illustrated radar target recognition based on wave synthesis is proposed in this dissertation. A theo-ry system on E-pulse has been structured completely through data of the transient electromagnetic simulation about radar tar-get and pole distillation precisely. Finally, the electromagnetic simulation on stealth plane target (F22, F35) and their cal-culating instance for target recognition rate are provided.

In this paper,the examination result of the frequency diversity used to solve the Angle Glint of space non-co-operative target is analyzed, as the effective approach to the high sensitive detection. And then a new high sensitive detection method based on the diversity radar is proposed,which can improve signal-to-noise ratio with the help of the relativity be-tween the high resolution signals. The simulation shows that the method is effective in the high sensitive detection of space non-cooperative target.

In free space optical homodyne receiver that analyze Residual carrier COSTAS loop, Inter-satellite LEO-GEO laser communication link frequency analysis, result from Doppler frequency shift 10GHz in the maximum range, LEO-GEO inter-satellite laser links between Doppler rate of change in the 20MHz/s. The optical homodyne COSTAS receiver is the application in inter-satellite optical link coherent communication system. The homodyne receiver is the three processes: Scanning frequency, Locked frequency and Locked phase, before the homodyne coherent communication. The processes are validated in lab., and the paper presents the locked frequency data and chart, LO laser frequency with triangle control scanning and receiving optical frequency is mixed less 100MHz intermediate frequency, locked frequency range between 100MHz and 1MHz basically, discriminator method determines mixing intermediate frequency less 1MHz between the signal laser and the LO laser with the low-pass filter due to frequency loop and phase loop noise. When two loops are running, the boundary frequency of laser tuning is fuzzy, so that we must be decoupling internal PID parameters. In the Locked frequency and phase COSTAS loop homodyne receiver gave the eye-diagram with Bit error rate 10E-7.

In free space optical homodyne receiver that analyze Residual carrier COSTAS loop, in the pointing and communication phase with laser terminal analyze free space link optical power penalty and pointing power penalty. In the conforming bit error rate with BPSK homodyne receiver dues to the minimum receiver optical power, in the same way the relation between receiver optical power and homodyne locked phase error variance, and the relation between receiver optical power and homodyne optimum equivalent noise loop bandwidth, all the more loop filter design parameter is variable with receiver optical power. In simulation COSTAS loop homodyne locked phase error deviation and loop bandwidth, when the receiver power is more -50dBm and less -40dBm in the signal trace, COSTAS loop parameter is not appreciable on the whole. Locked phase loop is integrated in the relation between baseband phase error deviation and carrier frequency shift, when baseband phase error is 10 degree, carrier frequency shift about above 100MHz.

In this paper,on the basis of the costas OPLL configuration,costas OPLL mathematical model and phase noise were showed,then the bandwidth,linewidth and optical power splitting ratio were then analyzed and computed.All these results in this thesis can provide theoretical supportment for intersatellite coherent optical communication system.
