Search Plan Variables

Question 1

Concept of Search Planning

Answer 1

Detection S W

Question 2

Sweep Width (W)

Answer 2

Width of a swath centered on the SRU’s track where the probability of detection is equal inside and out.

Question 3

Sweep Width Concerns

Answer 3

As the distance increases, the probability of detection decreases A detection probability is not a great measure of detectable sweeps Based on the quality of search object, search method, environmental conditions, SRU fatigue status.

Question 4

Sweep Width Correction

Answer 4

W= W_u x F_w x F_f x F_v

W_u = Uncorrected Sweep Width

F_w = weather

F_f = Fatigue

F_v = Speed Correction (Aircraft Only)

Question 5

What type of search objects are Visual Distress Signals

Answer 5

Active

Question 6

What are the types of Radars?

Answer 6

Side, Forward, Surface

Question 7

Track Spacing

Answer 7

Distance between track legs

SAR planner can can change spacing

Question 8

Coverage Factor

Answer 8

Sweep Width (W) / Track Spacing (S)

Question 9

Probability of Detection

Answer 9

Measured probability of detecting an object under “ideal” or “normal” conditions

Question 10

Maximizing Available Effort (Z)

Answer 10

Z= V * W * T : Searchable Area based on W

A = V * S * T : Search area based on S

T = Search Endurance
