“…And some novel and modified types of radar waveforms are provided. References [6] introduces many applications on the waveforms design of modern radar system, we mainly provide some radar waveforms with combined modulation, as shown below. To avoid the redundancy and overlap of signal spectra, the increase of frequency can be chosen as n B .…”

Abstract. This paper presents a task scheduling model based on intelligent signal environment cognition is provided to analyze the phased array radar resource scheduling in complex combat environment. The traditional priority of scheduling methods can't be satisfied to the needs in practice. According to the work mode and task of the phased array radar, some complex modulated signal waveform was established and WVD time-frequency transform was used to preprocess the features such as position of geometry center, polarimetric characteristics and et al which are provided to classifier and obtain the task priority. To overcome the weakness of classical scheduling algorithm, a novel task scheduling algorithm is provided which is based on Gaussian Process multitask classification. The method can effectively improve the performance of the radar scheduler and make the task scheduling more feasibly and practical.

“…Even when the threat transition to water, "sea surface can limit the observation of low-altitude targets by surface or low altitude radars" (Curry 2011). Radar terrain masking refers to the radar horizon range were the line-ofsight (LOS) of the radar is blocked by terrain or limited by sea surface (Curry 2011). The observation of low-altitude targets by surface or low-altitude radars can be masked by the terrain or be limited by the sea surface (Curry 2011).…”

“…Radar terrain masking refers to the radar horizon range were the line-ofsight (LOS) of the radar is blocked by terrain or limited by sea surface (Curry 2011). The observation of low-altitude targets by surface or low-altitude radars can be masked by the terrain or be limited by the sea surface (Curry 2011). When taken as a whole, these characteristics provide UAVs with a distinct advantage over war ships that need to establish robust procedures in order to protect against their inherent vulnerability in these operating conditions.…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instruction, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

AGENCY USE ONLY (Leave blank)2. REPORT DATE September 2015 This paper examines the need for a UAV Swarm Risk Assessment Tool and how it can assist the Navy's decision makers in assessing risk of UAV swarm threats in littoral environments, near potentially hostile countries, based on the latest intelligence. REPORT TYPE AND DATES COVEREDHuman-centered design principles help determine the needs of experienced battle commanders. These needs form the basis of requirements and functional analysis. The system design concept consists of several parts: discrete-event simulation of UAV swarm attacks using ExtendSim, statistical analysis of the simulation data using Minitab, and a graphical user interface (GUI) that evolved as a web-app prototype written in MATLAB.Data from the simulation is analyzed and used to generate equations that calculate the effect of critical factors: physical environment, number of UAVs, distance from land, and the ship's defensive weapons. The GUI uses these equations to provide users with the capability to vary those critical factors and analyze different courses of action and risk. The physical GUI web-app can be used as-is, tailored or expanded. The paper concludes with an analysis of the actual GUI prototype built for UAV swarm risk assessment and how it meets user needs.14.
