Abstract

A sequencer for use with an Electronic Warfare system consisting of one or more transmitters and receivers including one or more desired operations; a processor in communication with a memory; the memory storing instructions executed by the processor to sequence the one or more desired operations; an output connected to each of transmitter and receiver devices of the transceiver to control power-up and power-down sequences of the transmitter and receiver devices; wherein the instructions to sequence the one or more operations include instructions to prioritize a high-priority transmit operation such that the high-priority transmit operation is carried out in real-time upon request.

Claims

1. A sequencer for use with an Electronic Warfare system consisting of one or more transmitters and receivers comprising:

a processor in communication with a memory;

said memory storing instructions executed by said processor to sequence said one or more desired operations;

an output connected to each of transmitter and receiver devices of the transceiver to control power-up and power-down sequences of said transmitter and receiver devices;

wherein said instructions to sequence said one or more operations include;

instructions to prioritize a high-priority transmit operation such that said high-priority transmit operation is carried out in real-time upon request

wherein said high-priority transmit operation comprises a jammer operation;

wherein said one or more desired operations are selected from the group consisting of a jammer transmit burst, an electronic support signals intelligence (SIGINT) synchronous receiver burst a SIGINT asynchronous receive burst, a tactical communications (TC) transmit burst, and a TC receive burst;

wherein upon a condition in which each of said desired operations are requested, the instructions to sequence include instructions for the transceiver to;

transmit a jamming signal burst;

receive a TC burst;

transmit a TC burst;

receive a SIGINT synchronous burst;

receive a SIGINT asynchronous burst; and

,

transmit the jamming signal burst.

2. The sequencer according to claim 1, wherein a guard interval is implemented between successive transmit and receive operations.

3. The sequencer according to claim 1, wherein for receive operations, the sequencer instructions include instructions for placing the receiver in a state selected from the group consisting of idle, auto automatic gain control (AGC), on-demand AGC, manual gain control, capture and band select.

4. The sequencer according to claim 1, wherein for jammer transmit operations, the sequencer instructions include instructions for operating the transmitter in a mode selected from the group consisting of spot jamming at a given frequency and sweep jamming at a given band, and any of the above in combination with arbitrary waveform jamming stored a priori in memory or generated from user parameters on-the-fly.

5. An apparatus comprising

a system consisting of one or more transmitters and receivers;

a sequencer as defined in claim 1 for sequencing receive and transmit operations of said transceiver.

6. A method for sequencing transceiver transmit and receive operations comprising

receiving a signal requesting one or more desired operations;

sequencing by a sequencer said one or more desired operations to prioritize a high-priority transmit operation such that said high-priority transmit operation is carried out in real-time upon request;

controlling power-up and power-down sequences of transmitter and receiver devices of the transceiver in response to said sequencing;

wherein said high-priority transmit operation comprises a jammer operation;

wherein said one or more desired operations are selected from the group consisting of a jammer transmit burst, an electronic support signals intelligence (SIGINT) synchronous receiver burst a SIGINT asynchronous receive burst, a tactical communications (TC) transmit burst, and a TC receive burst;

wherein upon a condition in which each of said desired operations are requested, the instructions to sequence include instructions for the transceiver to;

transmit a jamming signal burst;

receive a TC burst;

transmit a TC burst;

receive a SIGINT synchronous burst;

receive a SIGINT asynchronous burst; and

,

transmit the jamming signal burst.

7. The method according to claim 6, wherein a guard interval is implemented between successive transmit and receive operations.

8. The method according to claim 6, wherein for receive operations, the sequencer places the receiver in a state selected from the group consisting of idle, auto automatic gain control (AGC), on-demand AGC, manual gain control, capture frame and band select.

9. The method according to claim 6, wherein for jammer transmit operations, the sequencer operates the transmitter in a mode selected from the group consisting of spot jamming at a given frequency and sweep jamming at a given band, and any of the above in combination with arbitrary waveform jamming.
