Question

Suppose we have 3 sensors observing a scene. What is the observation at the i-th sensor when the target is absent (H₀ is true) denoted as Yᵢ?

A) Y₀, Y₁, Y₂
B) Y₁, Y₂, Y₃
C) Y₂, Y₃, Y₄
D) Y₃, Y₄, Y₅

Answer 1

The observation at the i-th sensor when the target is absent is denoted as Yᵢ. In this case, Y₀, Y₁, and Y₂ are the observations from the 3 sensors.

Step-by-step explanation:

The observation at the i-th sensor when the target is absent, under the assumption that H₀ is true, can be denoted as Yᵢ. In this case, there are 3 sensors observing the scene, so the observations would be Y₀, Y₁, and Y₂. Therefore, the correct option is A) Y₀, Y₁, Y₂.
