Unreferenced date December 2009 Image AcousticHomingDiagram.svg right thumb 150px An illustration of steering based on sound volume Acoustic homing is a system which uses sound to guide a moving object, such as a torpedo . Acoustic homing can be either Passive or Active in nature. Using Passive, the system is designed to move either toward or away from a sound, and may also be designed to move only toward certain types of sounds to the exclusion of others. While Active is a true Sonar . The system emits a sound pulse, that reflects off objects and then back to the system. Where the system processes the echos to determine the proper response. Method An object can be equipped with two or more acoustic transducers , which function as loudspeaker speakers and microphones . If a transducer receives a sound louder than that received by the other transducer, the object turns in the transducer s direction. If the object is to manoeuvre in three dimensional space, more than two transducers are needed. Typically, more than three transducers are used, and arrays of over 100 are not unknown. A large number of transducers allows for more accurate steering. Uses Acoustic homing is useful in weapons , specifically torpedo es. Torpedoes can be made to move toward ships using acoustic homing.

When first heading out to sea, the animals are carried out by tides and currents with little swimming involved.

more footnotes date October 2007 Active radar homing is a missile guidance method in which a guided missile contains a radar transceiver and the electronics necessary for it to find and track its target autonomously. NATO brevity code for an active radar homing missile launch is Fox Three . Advantages There are two major advantages to active radar homing Because the missile is tracking the target, and the missile is typically going to be much closer to the target than the launching platform during the terminal phase, the tracking can be much more accurate and also have better resistance to Electronic countermeasures ECM . Active radar homing missiles have some of the best kill probability kill probabilities , along with missiles employing track via missile guidance. Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, and in the case of a mobile launching platform like an aircraft, can actually exit the scene or undertake other actions while the missile homes in on its target. This is often referred to as fire and forget capability and is a great advantage that modern air to air missile s have over their predecessors. Disadvantages There are three major disadvantages to active radar homing Since the missile has to contain an entire radar transceiver and electronics, it was until recently difficult to fit all of this into a missile without unacceptably increasing its size and weight ... and Chaff radar countermeasure deploy countermeasures .

Refimprove date February 2009 Semi active radar homing , or SARH , is a common type of missile guidance system, perhaps the most common type for longer range Air to air missile air to air and surface to air missile systems. The name refers to the fact that the missile itself is only a passive radar passive detector of a radar signal provided by an external offboard source as it reflects off the target. NATO brevity code for a semi active radar homing missile launch is Fox One . Concept The basic concept of SARH is that since almost all detection and tracking systems consist of a radar system, duplicating this hardware on the missile itself is redundant. In addition, the Angular resolution resolution of a radar is strongly related to the physical size of the antenna, and in the small nose cone of a missile there isn t enough room to provide the sort of accuracy needed for guidance. Instead the larger radar dish on the ground or launch aircraft will provide the needed signal and tracking logic, and the missile simply has to listen to the signal reflected from the target and point itself in the right direction. Additionally, the missile will listen rearward to the launch platform s transmitted signal as a reference, enabling it to avoid some kinds of radar jamming distractions offered by the target. Contrast this with beam riding systems, in which the radar is pointed at the target and the missile keeps itself centered in the beam by listening to the signal at the rear of the missile body. In the SARH system the missile listens for the reflected signal at the nose, and is still responsible for providing some sort of lead guidance. The disadvantages are twofold One is that a radar signal is fan shaped , growing larger, and therefore less accurate, with distance. This means that the beam riding system is not accurate at long ranges, while SARH is largely independent of range ... missile SM 2 , incorporate terminal semi active radar homing TSARH .

This Homingpigeonhoming behaviour is different from that of birds that show ...Domestic pigeonPigeon s have featured in numerous experiments in comparative psychology , including experiments concerned with animal cognition , and as a result we have considerable knowledge of pigeon intelligence . Available data show, for example, that Pigeons have the capacity to share attention between different dimensions of a stimulus, but like humans and other animals their performance with multiple dimensions is worse than with a single stimulus dimension. Pigeons can be taught relatively complex actions and response sequences, and can learn to make responses in different sequences. Pigeons readily learn to respond in the presence of one simple stimulus and withhold responding in the presence of a different stimulus, or to make different responses in the presence of different stimuli. Pigeons can discriminate between other individual pigeons, and can use the behaviour of another individual as a cue to tell them what response to make. Pigeons readily learn to make discriminative responses to different categories of stimuli, defined either by arbitrary rules e.g. green triangles or by human concepts e.g. pictures of human beings .
