Guided munition with passive homing to a GPS jammer

A modular radio frequency (RF) seeker for selective connection with a projectile, the modular RF seeker comprising:

• a plurality of RF antennas, wherein at least two RF antennas are spaced apart from each other at a distance that is less than one wavelength of a signal band of interest that is to be detected by the modular RF seeker;
• and
• a modular connector that modularly connects with another portion of the projectile, wherein when modularly connected, the plurality of RF antennas are in operative communication with a guidance kit on the projectile that guides the projectile toward at least one signal jammer emitting a signal at the signal band of interest.

A method comprising:

• installing a radio frequency (RF) seeker on a guided munition, wherein the RF seeker receives a signal from a signal jammer, wherein the RF seeker has at least two antennas that are spaced apart from each other at a distance that is less than one wavelength of the signal that is to be detected by the RF seeker;
• and
• installing command and control logic on the seeker, wherein the command and control logic receives data from the RF seeker based on the signal received at the RF seeker, wherein the command and control logic guides the guided munition to the signal jammer, wherein the guided munition is configured to detonate near the signal jammer and thereby disable the signal jammer.
