İfrat aşağı tezlik (İAT) diapazonuna malik uzaqlaşdırılmış hərbi otürücü sahələrinin elektromaqnit (EM) tədqiqi ən mobil və ucuz geofiziki üsullardan biridir. Hazırda bu üsul müxtəlif yataqların axtarışında, səthəyaxın yeraltı suların kəşfiyyatında, arxeolojı tədqiqatlarda və geoloji xəritələnmədə tətbiqini tapmışdır. Geofiziki tətqiqatlar üçün dünyanın müxtəlif regionlarında yerləşmiş onlarla İAT – ötürücülərdən istifadə oluna bilər. Müxtəlif tezliklər və qeyd olunan EM – şüalanmanın gəlmə bucağı təfsirdə əlavə üstünlük əldə etməyə imkan verir. FUDR (Qərb nəşrlərində VLF abbreviaturasından istifadə olunur) üsulu ilə tədqiqatda EM sahəsinin həm elektrik, həm də maqnit tərtibçilərindən istifadə olunur
Adətən EM sahəsinin maqnit komponentinə (H) üstünlük verilir. FUDR üsulunun geniş istifadəsi EM sahəsinin müvəqqəti varia-siyalarının aradan qaldırılmasının etibarlı üsulların olmaması, relyefin kəskin dərə-təpəliyinin təsiri və FUDR anomaliyaların miqdari təfsirinin proseduru ilə məhdudlaşmışdır. Bu problemlər uğurla həll edilmiş və vahid metodik sistemdə birləşdirilmişdir. Zamanda variasiyaların təsirini istisna etmək üçün xüsusı filtrasiya proseduru hazırlanmışdır. Korrelyasiya üsulu ərazinin dərə-təpəliyinin təsi-rini əsaslı azaltmağa imkan verir. FUDR anomaliyalarının miqdari təfsiri üçün mürəkkəb geoloji-geofiziki şəraitlərdə maqnit kəşfiyyatında hazirlanmış müasir üsullardan istifadənin mümkünlüyü sübut edilmişdir. Nəhayət, intensiv geoloji əngəllər fonunda gizlin obyektlərin aşkar olunması üçün orijinal statistik, informasion və veyvlet-alqoritmlərdən istifadə edilməsi təklif edilmişdir. Hazirlan-mış interpretasiya sisteminin əsas komponentləri Qafqazın polimetal və mis yataqlarında müvəffəqiyyətlə tətbiq edilmişdir.
