“…The multispectral system can see down into the water column to some depth depending on water clarity. In clear water, such as in Hawaii, detections as deep as 50 meters are routinely made [5]. As the track is flown, the multispectral data is recorded and processed.…”

Determining marine mammal densities is a complex problem that has been ongoing for many decades. Modern approaches use a combination of sophisticated acoustic monitoring and highly trained visual observers from both ships and aircraft. New camera systems with automatic detection algorithms offer the option to do quantitative airborne surveys safely and quickly. This paper presents a discussion on the various methods of calculating marine mammal densities and demonstrates how all these methods can work together to present quantitative density measurements.

This work presents an electro-optical multispectral capability that detects and monitors marine mammals. It is a continuance of Whale Search Radar SBIR program funded by PMA-264 through NAVAIR. A lightweight, multispectral, turreted imaging system is designed for airborne and ship based platforms to detect and monitor marine mammals. The system tests were conducted over the Humpback whale breeding and calving area in Maui, Hawaii. The results of the tests and the system description are presented. The development of an automatic whale detection algorithm is discussed as well as methodology used to turn raw survey data into quantifiable data products.

The Navy recently began investing in the design of mission-specific payloads for the Small Tactical Unmanned Aircraft System (STUAS). STUAS is a Tier II size UAS with a roughly 35 pound mission payload and a gimbaled generalpurpose electro optical/infrared (EO/IR) system. The EO/IR system is likely composed of a video camera in the visible, a mid-wave infrared (MWIR) and/or a long-wave infrared (LWIR) for night operations, and an infrared marker and laser range finder.Advanced Coherent Technologies, LLC (ACT), in a series of SBIR efforts, has developed a modular, multi-channel imaging system for deployment on airborne and UAV platforms. ACT's system, called EYE5, demonstrates how an EO/IR system combined with an on-board, real-time processor can be tailored for specific applications to produce realtime actionable data. The EYE5 sensor head and modular real-time processor descriptions are presented in this work. Examples of the system's abilities in various Navy-relevant applications are reviewed.Keywords: Electro-optical system, UAS payload, marine mammal mitigation, search and rescue, surf zone and shallow water mine countermeasures INTRODUCTION/BACKGROUNDOver the last few years, ACT has been developing and testing enhanced electro-optical and infrared (EO/IR) imaging systems in a variety of applications. The systems are designed to fit within a Tier II UAS size, weight, and power (SWAP) budget and to be modular enough to easily switch between applications. The system, collectively called EYE5, is basically composed of a sensor (camera) head and an acquisition/processing system tailored for a specific application to produce real-time actionable information. Applications have included polarization (Stokes Vector) imaging [1] , marine mammal detection and tracking [2,3] , homeland security [4] , littoral zone reconnaissance [5] , and others [6] .This paper presents the EYE5 modular sensor description and the data acquisition/processing systems. In addition, results from various data collects and demonstrations are presented from three distinct applications: marine mammal detection, littoral zone characterization, and border security. SYSTEM DESCRIPTION Sensor head EYE5The EYE5 turreted sensor system is a lightweight, stabilized, computer controlled, multi-camera image acquisition system capable of acquiring color video, infrared, and multispectral images simultaneously. The ability of the system to acquire using all of these sensors provides the maximum amount of flexibility for the user and enables them to use a single payload for a wide variety of missions.
