Optical Satellite Multiobjective Genetic Algorithms for Investigation of MH370 Debris

DOI: 10.4018/978-1-7998-1920-2.ch009

Abstract

At present, there is no precise method that can inform where the lost flight MH370 is. This chapter proposes a new approach to search for the missing flight MH370. To this end, multiobjective genetic algorithms are implemented. In this regard, a genetic algorithm is taken into consideration to optimize the MH370 debris that is notably based on the geometrical shapes and spectral signatures. Currently, there may be three limitations to optical remote sensing technique: (1) strength constraints of the spacecraft permit about two hours of scanning consistently within the day, (2) cloud cover prevents unique observations, and (3) moderate information from close to the ocean surface is sensed through the scanner. Needless to say that the objects that are spotted by different satellite data do not scientifically belong to the MH370 debris and could be just man-made without accurate identifications.

Review Of Mh370 Debris Floated In Southern Indian Ocean

There is plenty of MH370 debris collected from the Southern Indian Ocean. The former is a plane flaperon which was found on Réunion Island, on 29 July 2015. The latter discoveries of debris were in Mozambique, South Africa, Rodrigues Island (Mauritius), and Tanzania, which have confirmed belong to the missing MH370. Conversely, two debris found in Mozambique in December 2015 and February 2016, respectively, are almost confirmed from the missing aircraft. Correspondingly, other confirmed fragments of debris initiated in South Africa and Rodrigues Island. Moreover, the wing flap found in Tanzania has been confirmed as instigating from MH370 (Figure 1).

Summary of MH370 debris found

The flaperon is a 2.7 metre-long moveable part on the trailing edge of the wing, used to increase drag for takeoff and landing, and to bank the aircraft. The meter long-metal piece found in Mozambique in December 2015. Then the horizontal stabilizer, which is the right-hand tail section of a Boeing 777 found on 28 February 2016 in Mozambique. Moreover, the Engine cowling segment of 72 cm long found in South Africa on 21 March 2016.

The only interior part of the plane yet discovered, this piece, known as part four, was judged by experts to be a panel segment from the main cabin, associated with the Door R1 closet. It is found on Rodrigues Island, Mauritius, on 30 March 2016. On 23 June 2016, the wing flap found in Pemba Island, Zanzibar. The latter two unconfirmed debris is found by a local fisherman in Southeast Madagascar, on September 2016 (Minchin et al., 2017).

Briefing Of Satellite Images Tracked Debris

Four optical satellite sensors with different spectral signature and resolutions have claimed to survey countless MH370 debris in the Southern Indian Ocean. These sensors involve WorldView-2 (WV2), Gaofen (GF-1), Pléiades 50 cm global high-resolution satellite, and Thaichote satellite (Table 1).
