Devices and methods of providing response pulses in response to threat pulses are general described. The threat pulses are detected, identified and validity determined using reprogrammable firmware. Threat pulses are extracted from memory and the amplitude, frequency, phase, length and timing modified to generate a coherent set of superposed response pulses in response to the threat pulses. The modifications are calculated in situ using parameterization, rather than being based on tables. Multiple response pulses in response to different threat pulses are simultaneously generated, combined and transmitted in a single channel. Partial pulse capability and the capability to create a weighted and modulated composition of multiple response pulses is provided.
