Generating MD Signals to Test EW / Radar Systems
Application Notes
Modern Electronic Warfare (EW) systems are designed to monitor a speciied environment for Radar and communication transmission stations, whether friend or foe. An important task for the EW receiver is to detect incoming signals (waveforms) and identify exactly which station or stations they are coming from. The information coming from a signal transmission station includes the station’s location, speed, waveform types, and frequency bands. The EW receiver must be able to analyze signal information from all transmission stations.
In reality, the signal appearing at the EW receiver input is a combination of signals from different Radar or communication transmission stations with complex information for the location and speed of the stations, as well as time waveforms and the frequency bands of transmitted signals. To test the EW receiver, a test signal with the following characteristics is needed:
- It must come from multiple Radar and communication transmission stations.
- Each component of the EW receiving signal must include information from the transmission station on its location (e.g., longitude, latitude and attitude) and speed, as well as the time waveform from the station and the signal’s frequency-domain information.
- It must form multi-emitter, overlapping or non-overlapping signals.
