The 15 pages that link to Radar astronomy, each with the reason it gives.

• Astronomical unitRelated: Radar measurements greatly improved estimates of Solar System distances before the unit's exact definition.

• Orbit determinationRelated: Radar range and Doppler measurements can constrain orbits differently from optical angles.

• Mercury's perihelion precessionRelated: Radar ranging to Mercury improved measurements of its orbit and tests of relativistic predictions.

• Planetary defenseRelated: Radar can refine the distance, motion, and shape estimates of nearby asteroids.

• Yarkovsky effectRelated: Radar astrometry made the small orbital displacement of Golevka measurable.

• Near-Earth objectRelated: Radar can refine an object's distance, rotation, and orbit during close approaches.

• Arecibo ObservatoryNarrower topic: Arecibo could transmit powerful radar signals as well as receive distant radio emissions.

• Gravitational parameterRelated: Radar measurements of satellite orbits can constrain a planet's gravitational parameter.

• Shapiro time delayNarrower topic: Planetary radar provided the early signal paths and timing measurements for the test.

• YORP effectRelated: Radar measurements of asteroid shape and rotation made a direct YORP test possible.
