description The invention discloses a wind speed measuring device for a low-pressure high-speed Mars wind tunnel and a precision improving method thereof. The device comprises a laser (1), an L-shaped pitot tube (2), a CCD camera (3), sand dust (4), a Mars wind tunnel (5) and a lens (6), the sand dust (4) is evenly scattered in the Mars wind tunnel (5), the laser (1) is fixedly arranged at the top end of the Mars wind tunnel (5), the lens (6) is fixedly arranged below the laser (1), the L-shaped pitot tube (2) is obliquely inserted into the upper portion of the Mars wind tunnel (5), a total pressure hole of the L-shaped pitot tube (2) is aligned with the incoming flow direction, the CCD camera (3) is installed in the vertical direction of the sheet light plane, and after the CCD camera (3) is installed, the shooting area is the area in front of the L-shaped pitot tube (2). The problem that the wind speed measurement requirement of the low-pressure high-speed Mars wind tunnel test cannot be met in the prior art is solved.
