Eastern OptX is showing a radar target scenario generator designed to put a radar test range on your test bench.
“There is a need for more repeatable and accurate simulations. On-air testing can be very costly due to variables such as temperature, rain, and wind. These factors make repeatability difficult, if not impossible,” said Jerry Lomurno, president, Eastern OptX.
The Eastern OptX Series 1100 Radar Target Simulator is a true propagation path replicator. The Series 1100 receives the signal transmitted from a radar system and adds the round-trip propagation delay associated with the target distance. That signal is then output to the radar receiver.
The radar input/output (I/O) may be connected directly to the Series 1100 or detected and transmitted using a user-specified antenna. For a moving target, the system will add the appropriate Doppler shift associated with the target speed and radar frequency.
The Series 1100 is broadband with ranges up to 40 GHz with a dynamic range of over 100 dB. It operates with pulsed, frequency hopping, or continuous wave (CW) radars, and encryption or modulation schemes. It is expandable in range and operation modes to accommodate new system designs.
In a typical Series 1100 used with a common antenna radar system, the Series 1100 receives the signal transmitted from the radar, provides the necessary target delay, propagation loss, and Doppler, and then transmits it back to the radar receiver. Sixty (60) dB of I/O isolation is typical for most applications. Greater isolation can be achieved and can be ordered as an option.
Single antenna systems with octave band isolators are available for specific radar bands. Direct RF connection to radar and the Series 1100 without the external antenna is also common. The system operates with single antenna or phased array systems. Optional multiple target generation is available with single or multiple output emissions.
