“…Digital Radio Frequency Memory (DRFM) jammers have existed for several decades now, evolving from simple mono-bit devices to modern wideband, high dynamic range systems, with fully coherent receivers and transmitters [1]. Despite this, no published research has been conducted to understand the fundamental relationship of a DRFM system: the interaction between the deceptive waveform it generates and the radar receiver [2][3][4][5][6][7][8][9][10]. Understanding of the DRFM-radar interaction is fundamental to Electronic Attack (EA) design, allowing for the proper jammer waveform parameters (power, frequency, technique, etc.)…”

This paper describes the design, implementation, and testing of a novel multi-function software defined Radio Frequency (RF) system designed for small airborne drone applications. The system was created using an inexpensive Field Programmable Gate Array (FPGA) to combine a coherent linear frequency modulated radar transmitter and receiver, with a Digital Radio Frequency Memory (DRFM) jammer for use with a common RF aperture in simultaneous operation. The system was implemented on a Xilinx Kintex-7 FPGA with a wideband analogue-to-digital/ digital-to-analogue (ADC/DAC) converter mezzanine board and tested using hardware-in-the-loop mode to validate its performance. This is the first known account of an integrated multifunction electronic attack and radar system on a single chip, capable of performing a simultaneous, not time shared, operation.
