A passive view of the electromagnetic environment

ELINT passively receives signals transmitted by external radars and analyses their characteristics. With suitable receiving and direction-finding equipment, it supports classification and location estimates. The sensor does not need to illuminate the observed source; the aircraft's separate communication links may still transmit.

From a detected pulse to actionable context

Sorting signals and associating them with locations helps recognise emitter behaviour and distinguish fixed, temporary and moving sources. Correlation with EO and SAR gives analysts stronger evidence for classification from a single platform.

CRFS

RFeye Node 100-18 LW

Passive RF receiver

Catalogue alternative · integration unconfirmed

A wideband receiving module for recording and subsequent analysis of the radio spectrum.

Receive frequency range
9 kHz–18 GHz
Instantaneous bandwidth
100 MHz
Sustained I/Q streaming bandwidth
12.5 MHz
Network interface
1 GigE
RF inputs
3

100 MHz bandwidth does not mean continuous recording of that entire bandwidth. Confirm weight and antenna assembly: the manufacturer's introduction lists 1.98 kg, while its table lists 1.95 kg.

Rohde & Schwarz

EM200

Compact monitoring receiver

Catalogue alternative · integration unconfirmed

A receiver for spectrum observation and I/Q output to downstream processing.

Frequency range
8 kHz–8 GHz
Real-time bandwidth
40 MHz
I/Q streaming: standard / option
1 MHz / 40 MHz
Weight
Approximately 3.5 kg
Supply voltage
10–32 V DC
Typical power, depending on options
18–20 W

Figures are from the EM200 v1.00 fact sheet. Without suitable antennas, options and analysis, the receiver is not a complete direction-finding or ELINT system. Airborne integration is not confirmed.
