UPPER SADDLE RIVER, N.J. – Pentek Inc. in Upper Saddle River, N.J., is introducing the model 71821 data converter XMCembedded computing module for engineers building digital RF memory (DRFM) radar applications.
The newest member of the Jade family of data converter XMC modules, the model 71821 is for applications in which multi-channel inputs can digitize an incoming RF input signal at bandwidths to 80 MHz and then generate a processed version of that RF signal as an analog output with very low and deterministic latency.
It is a three-channel, 200 MHz, 16-bit A/D, with multiband digital down converters (DDCs) and one digital upconverter (DUC) to two 800 MHz 16-bit D/As, XMC module based on the Xilinx Kintex Ultrascale FPGA and can be used in many high-performance applications.
An incoming radar pulse is digitized and sent to the FPGA, which can apply a range of DSP algorithms before delivering the modified signal to the D/A for transmission back to the radar to simulate a reflected pulse.
These algorithms are intended to confuse, deceive, or disable the radar, depending on mission objectives. Being a coherent representation of the original signal, the transmitting radar will not be able to distinguish it from other legitimate signals it receives and processes as targets.
If the signal is stored in memory, it can be used to create false range targets both behind (reactive jamming) and ahead of (predictive jamming) the target intended for protection. Slight modifications in frequency simulate Doppler shifts to create false target velocity.
DRFM also can be used to create distorted phase-fronts, which is essential for countering monopulse radar angular measurement techniques.
The model 71821 XMC module is designed to operate with the wide range of carrier boards in PCI Express, 3U and 6U VPX, AMC, and 3U and 6U CompactPCI form factors, with versions for both commercial and rugged environments.
