Design of radar display of Indonesian airspace monitoring application

Abstract

In this research, the design and manufacture of radar display software using Plan Position Indicator (PPI) format for air surveillance radar application are presented. The PPI display shows interpretations of echo detections of radar signal reflected from the flying objects/targets. The detection results will be displayed on a circular 360ᵒ area, where the radar position is at the center. System configuration is done via interface from the display, by adjusting the level of transmit signal, by setting the gain for threshold, and by enabling moving target indicator (MTI) mode. The MTI mode only displays moving objects and no non-moving objects are shown such as mountains and buildings. Based on the results of this research, the PPI display shows the targets on the display according to its position, some desired targets can also be tracked, information on target, GPS location, target ID, required parameters, and some settings. The radar display fulfills all the required capabilities for air surveillance radar.

A Novel Airspace Planning Algorithm for Cooperative Target Localization

“…Particularly, under the circumstance where passive transducers are loaded on the mobile platform, apart from the solution of target's location, the mobile platform's planning in the maneuvering airspace also exerts great effects on the precision of the target's localization. Based on the different targets and shapes of planned airspace, airspace planning is generally classified into route planning [17][18][19][20][21][22] and region planning [23][24][25][26][27][28][29]. The former one performs the optimal planning of the aircraft's route and tracks by clarifying the starting point and restricting the terminal destination on the basis of the aircraft's overload capacity and GPS localization [18,20] and applying dynamic planning [19], cooperative planning [17,21], etc.…”

At present, solutions of airspace planning concerning cooperative localization platforms are still at the early stage.…”

“…The facilities include the signages and special landmarks that could help the victims to find the directions to safe exits through observation. Meanwhile, navigation sensors such as radar [2][3][4], inertial measurement units [5] or wireless positioning technologies [6] provide details information to the victims or rescuers about their current positions with respect to defined reference in the building. The latter focuses on the navigation models which study the optimal waypoints to the nearest or the fastest ways to the safe exits.…”
