Based on the detection field of capacitance proximity fuze is quasi-static-electric field

according to distribution feature of quasi-static-electric field is set up on the analogy of direction function of radio fuze

field distribution function of capacitance fuze is set up

and equifield intensity detection directional diagram of capacitance proximity fuze is nearly an ellipsoid

whose long axis is 20 % longer than the minor one

it validates the capacitance proximity fuze burst height disperses little while the missile and target intersect differently.
