Simulasi Deteksi Posisi dan Lintasan Roket Menggunakan Algoritma TDOA-Trilateration pada Sistem Radar Sekunder
ABSTRACT: Position and
trajectory detection of rockets is very nessesary for the lauch of rockets can
work as expected. If position and trajectory of rockets aren’t monitored
properly, it could be bad. Therefore, we need solutions to monitor the position
and trajectory rockets with the technical studies in particular. Rockets moves
with initial power and power when rockets fly until its produce acceleration.
The rockets movement are arranged by the law of mechanics orbital and its are
affected by the law of aerodynamics. The output result from this detection, will
be used as comparative data with the expected trajectory. Through this final
project, we simulate application of TDOA-Trilateration Algorithm for detect
position and trajectory of rocket on secondary radar system. Technique for get
distance between transceiver station and transponder is with find time
difference of transmit and receive signal between transceiver station and
transponder. This technique is called with TDOA (Time Difference Of Arrival).
After Distance between transceiver station and transponder is known,
three-dimensional position can be searched with Trilateration methode. This
prosses will be simulated with software Matlab R2008a. On the simulation
testing indicate that rockets position and trajectory which result from
simulation of rockets trajectory formation stage with simulation stage to
detect position and trajectory of rockets have the same x, y, z values.
However, there is one point of positioan which haven’t the same z value while
the z value is negatif. Variation values of D0, D1, and D2 (the placement of
Ground Station) aren’t influential to the detection values (x, y,z), but
influential to values of deltaT1, deltaT2, and deltaT3.
