If you approach your target on a perpendicular course, there is a defined relationship between AOB and Bearing.
Target Moving Left to Right:
Bearing 315° = AOB 45°stb
Bearing 340° = AOB 70°sbt
Bearing 350° = AOB 80°stb
Bearing 000° = AOB 90°stb
Target Moving Right ot Left:
Bearing 45° = AOB 45°pt
Bearing 20° = AOB 70°pt
Bearing 10° = AOB 80°pt
Bearing 000° = AOB 90°pt
