www.eravant.com | 424-757-0168 | support@eravant.com Copyright © 2023 by Eravant Final Rev 1.3 Radar Target Simulator, Direct Reading STR-793-12-D1 is a radar doppler simulator that operates at 78.5 GHz with a bandwidth of ±2.5 GHz and a WR-12 waveguide input/output. The simulator utilizes a single-sideband-modulator to modulate the incoming signal transmitted by the radar under test and sends back either a higher or lower band signal through a diplexer. The frequency-shifted signal is transmitted back to the radar under test as a Doppler signal. Target characteristics are adjusted by changing the I and Q channel frequency and phase. Siglent’s SDG1032X Waveform Generator or equivalent is recommended. The routing attenuation is adjusted by the direct reading attenuator.

  • Models with different operating frequencies are available under different model numbers.
  • A 78.5 GHz Radar Target Simulator with a level setting attenuator, instead of a direct reading attenuator, is available as model STR-793-12-L1.
  • Eravant reserves the right to change the information presented without notice.
  • Eravant has performed test and recommends Siglent’s SDG1032X Waveform Generator or equivalent in combination with our Radar Target Simulators. CAUTION:
  • Exceeding absolute maximum ratings shown will damage the device.
  • Any foreign objects in the waveguide will cause performance degradation and may damage or destroy the unit. (0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
