To detect mines by the explosive itself, several new techniques have been proposed; one of the most promising is 14N NQR. Design criteria allowing increase sensitivity of 14N NQR are discussed. It is shown that combination of 1H NMR with 14N NQR leads to selective excitation or a better S/N; in this case, a strong magnetic field has to be switched on and off. Whereas to detect anti-tank mines strong magnetic field should be applied.
