GROUND PENETRATING RADAR - FERRITE TRANSFORMER DETAILS

[vasileios]

Hi all,

I am implementing the circuitry for a GPR and I need INFO about the four Russian ferrite cores that are used.

Can anybody help please?

FERRITE DATA

M1=M140 K12X6X5 W1=W2=50 D=0.25

M2=M2000 B22 W1=10 W2=100 D=0.25

M3=M2000 2XK7X4X2 W1=6 W12=50 D=0.25

M4=M50 K12X6X5 W1=W2=20 D=0.25

Regards

Amateurs frequently use surplus ferrite core, that are rare standardized.

It is better to follow given inductances (by estimated area of use).

If you reach given inductance by approximately same number of turns (say till to +-10%) as author, then core you used should be OK.

M2000 , M50 and so on - it means magnetic permeability of the core material . K12x6x5 - this is a ring core dimensions in millimeters ( outer diameter , inner diameter , height ) . If you find a ferrite cores with a similar parameters , it must be OK .

Of course it's a good idea - if the author of the circuit gives this information ...
