Doppler Localization and Target Detection Using Different Codes by Qpsk Transmission Technique
نویسنده
چکیده
In this paper we transmit different complimentary codes using QPSK (Quadrature phase shift keying) modulation technique. The signal which is transmitted is scattered back from the target and send to the receiver for the demodulation. Using matlab a digital processing algorithm is designed for resolving range resolution and Doppler localization of a target using different complimentary codes like barker, golay, ternary. The autocorrelation is done for suppressing the sidelobes. By using QPSK technique and different codes the Doppler localization, target detection and range estimation is improved. KeywordsAuto correlation, QPSK, Golay complementary codes, Doppler localization.

Assessment of Weighting Functions Used in Oppermann Codes in Polyphase Pulse Compression Radars
Polyphase is a common class of pulse compression waveforms in the radar systems. Oppermann code is one of the used codes with polyphone pattern. After compression, this code has little tolerant against Doppler shift in addition to its high side lobe level. This indicates that the use of Oppermann code is an unsuitable scheme to radars applications. This paper shows that the use of amplitude wei...
متن کاملImproving Long PN-Code Acquisition in the Presence of Doppler Frequency Shifts
Wireless communication is the major form of connection nowadays. In most cases it exploits the benefits of the spread spectrum techniques to overcome channel introduced corruptions like Doppler residual frequency, noise, interference and jamming. These techniques also enhance the security and quality of the link. Using long spreading pseudo-noise codes provides further security for the link tho...
متن کاملSp-qpsk: a New Modulation Technique for Satellite and Land-mobile Digital Broadcasting
A new modulation technique, "SP-QPSK" (sinusoidal shaped d4-QPSK) suitable for land-mobile and satellite digital broadcasting systems applications is introduced. In digital data and/or sound broadcasting systems, which may have a relatively low bit rate transmission requirement, the residual phase noise introduced by the Doppler shift of moving vehicles presents a high bit error floor in cohere...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملDoppler and bearing tracking using fuzzy adaptive unscented Kalman filter
The topic of Doppler and Bearing Tracking (DBT) problem is to achieve a target trajectory using the Doppler and Bearing measurements. The difficulty of DBT problem comes from the nonlinearity terms exposed in the measurement equations. Several techniques were studied to deal with this topic, such as the unscented Kalman filter. Nevertheless, the performance of the filter depends directly on the...
