Dynamic interface for firmware updates
First Claim
1. A method of providing jamming techniques from an electronic warfare (EW) system, the method comprising:
- updating EW firmware by adding a new jamming technique to the EW firmware and changing parameters of one of the jamming techniques in the EW firmware;
storing parameter sets for a set of jamming techniques including jamming techniques other than those currently available by use of the EW firmware in a library of the EW system, the library storing a greater number of jamming techniques than a number of jamming sets able to be generated by the EW firmware, wherein the new jamming technique is added free from eliminating other jamming techniques;
indicating to an Operational Flight Program (OFP) that the EW firmware has been updated;
generating a jamming technique in the EW firmware using parameters transmitted by the OFP to the firmware, the same OFP being used to trigger generation of jamming techniques prior to and after the updating of the EW firmware; and
transmitting the jamming technique to provide countermeasures against a radar signal impinging on the EW system.

Abstract
An electronic warfare (EW) devices and a method of providing jamming techniques are generally described. Firmware is updated by eliminating an existing jamming technique, adding a new technique and/or changing parameters of one of the techniques in the firmware. Changing the technique parameters includes adding a new parameter, deleting an existing parameter, changing the range of values for an existing parameter and changing the order of the parameters to be transmitted by an Operational Flight Program (OFP) to the firmware to generate the technique. The OFP reads a published a register mapping specifying parameters to use in generating the jamming techniques in the EW firmware, a range of the parameters and an order of the parameters. The jamming techniques are generated using parameters transmitted by the OFP to the firmware. The same OFP is used to trigger generation of jamming techniques prior to and after the updating of the firmware.
