An ocean scientist named Peter is planning an experiment. He will deploy 7 acoustic sources, each at a depth of 1000 m and suspended on a long cable. The 7 sources will be deployed in a circle with 100 km radius around a long (5km) vertical receiving array. Each source will transmit its own signal defined as Sk(1), where k is the source number: sk(t) = cos(2π (at² + kẞt)) k=1,2,...7 0

Question

I need help with this problem and an explanation of the solution for the image described below. (Introduction to Signals and Systems)

An ocean scientist named Peter is planning an experiment. He will deploy 7 acoustic sources, each at a depth of 1000 m and suspended on a long cable. The 7 sources will be deployed in a circle with 100 km radius around a long (5km) vertical receiving array. Each source will transmit its own signal defined as Sk(1), where k is the source number: sk(t) = cos(2π (at² + kẞt)) k=1,2,...7 0<t≤10, where a 1.5 and ẞ = 50. Two other scientists, Lora and Matt, are planning to work in the same part of the ocean. They plan to transmit signals from a source on an undersea glider. The glider can move around the environment. The signal p(t) that Lora and Matt's glider will transmit is defined as: p(t) = (cos(2π fol)+1) cos(2π fel), where fo = 100 Hz and J = 240 Hz. Lora and Matt are trying to convince Peter that their glider signal will not interfere with any of his source signals, thus they should be allowed to broadcast their signals at the same time as his sources are transmitting. In addition, Lora and Matt say that Peter's sources will interfere with each other, so what's the point in protecting the source signals from their glider? Peter has asked you for your advice. What do you think? Will Lora and Matt's glider transmissions interfere with any of Peter's 7 sources? If so, which ones will it interfere with? Do Peter's 7 sources interfere with each other? Analyze the situation, and summarize your analysis below. Please include any calculations and/or plots that will help Peter, Lora, and Matt understand your results.
