If Radar1 located at 395 N 765 W locates an aircraft at a sl

If Radar1 located at 39.5 N, 76.5 W locates an aircraft at a (slant) range of 129.1 km, azimuth 330.18 º, and elevation 8.7 º, then what is the position (latitude, longitude, and altitude) of the aircraft, and at what range, azimuth, and elevation would Radar2, located at 39.5 º N, 77.5 º W observe this aircraft?

Linear algebra

Solution

height of plane = tan 8.7⁰ x 129.1 = 0.15124 x 129.1= 19.5 km

ground distance = 129.1 x cos8.7^o = 127.615 km

P location =
