Advantages And Disadvantages Of Miss Distance

Decent Essays

In the external guidance problem, the chief contributors to the miss distance are shown in figure (2-6) as mentioned in reference [35]:
Fig. (2-6). The main reasons of miss distance
The first reason is the heading error which is defined as the angle represents the deviation of the missile’s velocity vector from the collision course. When the initial value of the heading error is different from zero, the missile tries to compensate the difference and this attempt causes a delay for sitting on the collision course. So, this contributes positively to the miss distance at the termination of the engagement. Another significant reason of the miss distance is the target maneuver. Compared to a stationary target, it is more difficult first to detect and then to track a moving target [36].
Moreover, the disturbing effects such as the noises affecting the electro-optical part of the seeker and the radome refraction that occurs depending on the shape of the radome cause the seeker to generate the target information …show more content…

Unfortunately TVM has some limitations. For example, the data link could be suffer from jamming. Conversely, it is not occur with an active homing missile. Furthermore, this technique utilizes the ground radar to keep the target illuminated throughout the engagement. Thus, the aircraft equipped with anti-radiation missiles could detect and engage the SAM radar. Another drawback is that the missile must depend on the ground radar for guidance, so if the target hides behind hill, thus the missile cannot be able to detect reflected wave from the target which causes losing tracking of target. Some examples of missiles that use this kind of guidance are the Russian S-300PS, S-300F, S300-PMU, anti-aircraft, and anti-Cruise missile . Figure (2-12) shows the launcher of S-300 system.
