“…An analysis of the AFR coefficients  din () and D din () of ILAD will be performed numerically by introduc- ing the variations of various system parameters. Figure 3 shows the calculation results according to (14) and (15) by taking into account (17), (18) and (13) of the family of AFR diagrams  din () and D din () obtained for the isochronous oscillator ( = 0), at different levels of the synchronizing signal. Figure 4 shows the AFR diagrams D din () for various cases of an isochronous oscillator and non-isochronous oscillator (  0) with variations in the conditions of synchronization of the oscillator.…”

“…One of the most important parameters of both radio frequency and laser AD as well as AD with various types of modulation is the so-called feedback parameter (FBP), C FB = Δω AD τ, where ω AD is the autodyne frequency deviation value; τ is the delay time of the reflected microwave radiation [15], [18][19][20]. The physical meaning of this parameter FBP is the phase modulation index of the autodyne response.…”

This article presents the results of the autodyne (AD) frequency deviation research, which is simultaneously affected by its own reflected radiation and the external synchronization signal. The basic correlations are obtained for the injection-locked AD (ILAD) analysis in the case of a moving radar object. The amplitude-frequency characteristics are calculated for the transfer coefficient of the autodyne phase variations and the ILAD frequency deviation. The advantages of ILAD are shown compared to AD without synchronization. The theoretical research investigations are confirmed by experimental data obtained by the example of an oscillator made on the basis of the 8-mm Gunn diode.

The voltage is one of the important criteria for the evaluation of the electric energy quality, as well as the sign of reflecting the reactive power balance and reasonable distribution electric power system. Distributed voltage control is a kind of fast and effective controlling method. To deal with the complicated conditions of the divided boundary, this article leads into the concept of the temporal and spatial boundary constraint set, putting forward the method of spectral clustering partition of the boundary constraint set. Firstly, the way of obtaining the distributed numbers is given specific to the electric power net. Then, the voltage time series analysis is carried on the base of the space relationship. Betweenness, degree and other complex internet and intranet concept have been brought in to evaluate the importance of node, the definition of the partition degree has been made through the data visualization. Dividing the boundary node into whirlpool node and isolated node, dealing with them separately. When the voltage fluctuation takes place, the reason can be made clear, the prediction about chain fluctuation spreading tendency will be made and the regulation and control scheme will be given. Application in some province's electric power net system has saved the computing time and improved the response speed.
