US12680786 - Guided munition with passive homing to a GPS jammer

A modular radio frequency (RF) seeker may be modularly connected with a projectile having a diameter of about four inches or less. The modular RF seeker may have 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. 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 jamming signal at the signal band of interest.

The patent describes a guided munition equipped with a modular radio frequency seeker that can detect signals from jamming devices, allowing it to home in on and disable these jammers. The munition features a modular design with two portions that connect, enabling effective guidance through command and control logic based on data received from the RF seeker.

Claim 1

1 . A guided munition comprising: a modular first portion located at a front end of a guided munition; a modular second portion located rearward of the modular first portion, wherein the modular second portion selectively connects with the modular first portion; a radio frequency (RF) seeker that 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 command and control logic that receives data from the RF seeker based on the signal received at the RF seeker, and 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. a modular first portion located at a front end of a guided munition; a modular second portion located rearward of the modular first portion, wherein the modular second portion selectively connects with the modular first portion; a radio frequency (RF) seeker that 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 command and control logic that receives data from the RF seeker based on the signal received at the RF seeker, and 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.
