“…Such transmitters, in the form of miniature, microwave oscillators dedicated to specific radar band and synchronized with its signal, are devoid of the disadvantages of noise sources. Additionally, with a relatively simple design, they are able to generate interference in the radar frequency band, depending on the probe signal [5]. As a result, an oscillator of this type can be a kind of "intelligent" source of the interference signal, which may adapt in an analogue way, the generated signal to the parameters of the radar signal.…”

A typical block diagram of the injection-locked oscillator [5] is shown in Figure 7. As numerous publications show, the phenomenon of injection-lockingis quite widely used in practically designed microwave oscillators, used in, among others, radio communication systems [5].…”

“…A typical block diagram of the injection-locked oscillator [5] is shown in Figure 7. As numerous publications show, the phenomenon of injection-lockingis quite widely used in practically designed microwave oscillators, used in, among others, radio communication systems [5]. However, due to the fact, that the base source for all solutions based on this phenomenon is the publication of R. Adler [6], the application of injectionlockingfor the purpose of disturbing the microwave radars, requires certain modifications, in order to "adjust" the mechanism proposed by Adler.…”

The paper comprises the concept of application of low cost devices creating an active interference by emitting low power, which results in an effect comparable to that obtained with the use of expensive high power devices. Modern radars have many mechanisms that increase their resistance to interference, including active ones. In order to address this issue the use of synchronized sources of the interference is proposed. These sources generate signals in specific frequency bands that correspond to the working frequency of the device to be interrupted. The paper describes the concept of creating a dedicated, spatial interference with the use of miniature, microwave oscillators, which are synchronized by a signal intercepted from the device being interrupted.

“…Kurokawa's theory was also used to develop a locking bandwidth equation for transmission type injection-locked oscillators [6]. Further, equations for such electrically injection-locked oscillators have been used for predicting the locking bandwidth of optically injection-locked oscillators [4]- [5]. In recent years, optically injection-locked oscillators have attracted great interest because of their possible use in future optical communication systems, in applications ranging from microwave and millimetre-wave signal reception, phased array systems and optoelectronic clock recovery [7]- [12].…”

“…Compared with Adler's oscillator model, an additional circulator at the oscillator output in Kurokawa's model was used to separate the injection signal and the oscillator output signal. Adler's and Kurokawa's equations have been used widely to calculate the locking bandwidth for injection-locked oscillators [4,5]. Kurokawa's theory was also used to develop a locking bandwidth equation for transmission type injection-locked oscillators [6].…”
