The difficulties to countering terminal sensitive projectile are analyzed with the attacking process characteristics and sensitive detection principle of the typical terminal sensitive projectile in foreign countries. Results show that regional active jamming is difficult to effect for the extremely close detection distance and the smaller field of view of the terminal sensitive projectile. A single countermeasure method is failure for the high hit accuracy, which uses many kinds of sensitive means of detection. The terminal sensitive projectile has characteristic of "destroy when found", motor alone can′t escape. For the efficient charge ratio, protection cost is higher. And the development idea of terminal sensitive projectile countermeasure technology is briefly introduced.
