La description
Key Facts- Real time capability for echo generation
- Frequency coverage up to 40 GHz with one single generator and analyzer
- Excellent RF performance of R&S®SMW200A signal generator and R&S®FSW signal and spectrum analyzer
- Baseband flexibility of R&S®SMW200A (e.g. add interferers and noise)
- No external PC necessary
- Intuitive and easy to use graphical user interface
Brief Description The R&S®SMW-K78 radar echo generation option, in conjunction with the R&S®SMW200A vector signal generator and the R&S®FSW spectrum and signal analyzer, makes it possible to artificially generate radar signal echoes. These tests can be performed via a wired connection (conducted test) or via the air interface (over the air test), eliminating much of the need for time-consuming and costly field tests.

Test setups | radar under test (RUT) is directly connected to the R&S®SMW200A (+ R&S®FSW) via cable | conducted test |
RUT and R&S®SMW200A (+ R&S®FSW) are equipped with antennas and connected via air interface | over-the-air (OTA) test | |
Radar RX power setting | calculation of power received by RUT regarding two-way radar equation | radar equation |
power received by RUT is set manually | manual | |
Simulation setup | ||
System latency calibration | R&S®SMW-K78 measures the internal system (R&S®FSW + R&S®SMW200A) latency automatically (only available in transmit signal mode: external baseband via R&S®FSW + R&S®SMW-B10) | automatic |
user measures internal latency with external equipment (e.g. scope) | manual | |
Object configuration | ||
Object type | arbitrary object types can run at the same time | |
echo is not generated | off | |
echo for objects with variable range and constant velocity > 0 m/s is generated | moving | |
echo for objects with constant range and no velocity is generated | static | |
echo for objects with constant range and constant velocity > 0 m/s is generated | static + moving | |
Parameters common to all object types | ||
Object name | define 15-digit name | |
Range | ||
Setting range | use radar range ambiguity to reduce min. range: off | 2.1 km to 10 000 km |
use radar range ambiguity to reduce min. range: on | 0.0001 km to 10 000 km | |
Setting resolution | 0.1 m | |
RCS | power setting: radar equation | |

Parameters for moving objects | ||
Simulation mode | object moves back to start position with set velocity after reaching its end position | round trip |
Object velocity | ||
Setting range | the maximum Doppler shift of 190 kHz must not be exceeded | 0.001 ms to vmax vmax = 750 m/s or (190 kHz / 2f ) ? c, whichever is lower |
Setting resolution | 0.001 m/s | |
Parameters for static + moving objects | ||
