The apparatus of claim 8, wherein the processor comprises: a parametric magnetic field distribution model that models a substantially curved region in said target object as at least two linear objects. 11. The apparatus of claim 8, further comprising: an injector for injecting at least one additional signal into an object other than the target object to create the magnetic field; and wherein the processor further comprises a processor for using the injected at least one additional signal to generate a match. 12. The apparatus of claim 8, wherein the processor further comprises a parametric magnetic field distribution model at a receiver location r, the model including at least a term corresponding to B(r, ra,rb,Iab) having the form: where: B is the modeled magnetic field; Iabis a line current between points a and b on the target object; k is a multiplier; rais a first point on the target object; and rbis a second point on the target object. 13. The apparatus of claim 8 further comprising: a target object display. 14. The apparatus of claim 8, wherein at least one of said signal injector, magnetic field receiver, matching processor, and locating processor is mounted in a mobile platform. 15. The apparatus of claim 8, wherein at least one of said signal injector, magnetic field receiver, matching processor, and locating processor is mounted in a portable platform. 16. A computer program product for use in a computer adapted for locating a target object, at least a portion of which is buried, the computer program product comprising a computer readable medium for storing computer readable code means, which when executed by the computer, enables the computer to locate the target object, and wherein the computer readable code means includes computer readable instructions for causing the computer to execute a method comprising: injecting a signal into the target object; receiving a magnetic field radiated from the target object; determining parameters in a parametric magnetic field distribution model corresponding to the target object and at least one other object so that the difference between the model and the received magnetic field minimizes a preselected cost function; and locating the target object using parameters from said parametric magnetic field distribution model. 17. The computer program product of claim 16, wherein the computer readable code means further includes computer readable instructions for causing the computer to compute parameters of a parametric magnetic field distribution model at a receiver location 7, the model including at least a term corresponding to B(r, ra,rb,Iab) having the form: where: B is the modeled magnetic field; Iabis a line current between points a and b on the target object; k is a multiplier; rais a first point on the target object; and rbis a second point on the target object. 18. An apparatus for locating a target object, at least a portion of which is buried, comprising: means for injecting a signal into the target object; means for receiving a magnetic field radiated from the target object; means for determining parameters in a parametric magnetic field distribution model corresponding to the target object and at least one other object so that the difference between the model and the received magnetic field minimizes a preselected cost function; and means for locating the target object using parameters from said parametric magnetic field distribution model. 19. The apparatus of claim 18, wherein the means for determining further comprises: means for selecting a parametric magnetic field distribution model corresponding to at least two substantially linear objects. 20. The apparatus of claim 18, wherein the means for determining further comprises: means for selecting a parametric magne
