This is often the first actual ebook to present the community radar countermeasure approach. It explains intimately the systematic thought of combining radar and radar countermeasures from the viewpoint of the data acquisition of aim place, the optimization of the reconnaissance and detection, the built-in assault of the indications and amenities, and technological and criminal developments concerning the networked procedure. It achieves the mixing of the initiative and passivity, detection and jamming. The e-book explains how the approach locates goals, completes target identity, tracks goals and compiles the information.

Because the neighborhood types required to appreciate and keep watch over the iteration, distribution and deposition of air toxins develop into extra certain, the necessity to comprehend the designated results of hilly and mountainous terrain turns into extra acute. The alpine areas and the mountainous Mediterranean coasts have huge results at the method the pollutant burden is unfold of their components.

However, it is maximum when α ¼ 90∘ and α ¼ 270∘ , with the exposure radius being 1300 m in both cases. As a result, when using jammers to defend targets, we should deploy them in the main direction of the enemy’s attack, protruding or retreating a certain distance d, so that the exposure radius of the target in the main direction of the enemy’s assaulting aircraft becomes the smallest.

3 of the network radar countermeasure system. By simulation, we obtain the two-dimensional and three-dimensional diagrams of the power range under deployment No. 3 as shown in Fig. 15. In Fig. 15, “#”stands for a transmitting station and “*”stands for a receiving station. 68 % of the total area in the case of deployment No. 3, which indicates that proper deployment of transmitting and receiving stations can increase the two-dimensional power range, but the height of the three-dimensional power range of deployment No.

The power of the jamming signal can be superimposed at the receiver station. 22), m is the number of jammers, Pji is the transmitting power of 0 the ith jammer, Gji is the side lobe gain of the ith jammer, Pt is the transmitting power of the transmitter station in the system, Gt is the gain of the transmitter, and σ is the cross-section of the target. Thus, the detection area of the reconnaissance unit is the solution set of the following inequalities Ω: 8 m X > > > PCi > > > > i¼1 > > Kj > > PR > > > > 0 > > Pt G t G r λ 2 σ > > !
