Here are some thoughts about how to make RCIED countermeasures.
According to Ref. 1 over 300 US and coalition soldiers killed or wounded from Improvised Explosion Devices (IEDs) in a short period of time. IEDs are hidden roadside where military convoys drive by. An observer, located at a safe distance, transmits a command triggering the IED at the appropriate time. The damage caused depends generally on the number of IEDs emplaced, the explosive type and blast power, the armature of the convoy vehicles and speed of travel, the spacing between the convoy vehicles and the IED distance from the convoy at the moment of explosion. The last is also a function of the observer reaction speed, his remote control system speed of transmitting the detonating command, the time-length of that command, the detonator-explosive delay and it is also a function of the observer safety distance if transmission propagation time periods would be taken into account into a geometry model like the one shown in Fig. 1.
Fig. 1. The “IED system” includes the IED ellipse, which contains explosives, a remote control receiver with an antenna and a battery (or just a cell-phone), and also includes an observer (standing-off) who first aims at the target optically and then triggers the IED using RF. The observer – operator entity is an IED system requirement, because it is assumed that there are no other sensors and processing that would automatically trigger the IED on time. Sometimes is positioned together with the IED (suicide attacks).
