Doppler Effect (or Principle) and Its Application for Military Purposes. The Doppler (or more correctly Doppler) effect, first observed by C.J. D oppler of Prague in 1842, involves the apparent change in the frequency of light, sound, or electromagnetic waves observed while the source and the observation point are in motion relative to each other. The effect is commonly ob-... 

Evidently, both forces change direction with time as the individual rays associated with the source and the sink rotate. Also, the wavenumber, Eq. (110), formally is the conventional expression of course, k describes propagation of the electromagnetic wave. However, the origin of angular velocity co is the rotation of the source. 

Nonlinear optics entails the mixing of one (with itself in some cases) or more fields to produce a nonlinear polarization source term, which in turn can radiate a new electromagnetic wave (13,14). This term is usually written as... 

Fig. 3.4 Schematic drawing of an electromagnetic wave with the dependence on propagation time t and propagation direction x at a large distance from the generating source.

In contrast to coherent radiation emitted by laser sources, incoherent or non-co-herent radiation is characterized by elementary electromagnetic waves that do not have any phase relation in space and time. The production of incoherent excimer radiation in the UV or VUV region of the electromagnetic spectrum is made pos-...
