Modern radar systems often have the conflicting requirements of a large phased array antenna for increased power-aperture product and/or angular resolution versus wide instantaneous signal bandwidth for fine range resolution. Pulse-to-pulse diversity may also be desired as a countermeasure against coherent repeater jammers. Using the multicarrier nature of orthogonal frequency-division multiplexing to encode wide instantaneous bandwidth pulses we propose a novel digital phased array architecture which mitigates dispersion effects experienced when the array main beam is electronically steered off broadside. The result is the ability to transmit and receive wideband pseudo-random phase coded pulses with a phased array antenna. Simulation results are used to quantify the benefit of the architecture. An overview of digital orthogonal frequency-division multiplexing waveform generation is also provided.
Improvements in RF and digital technology have made digital array radar (DAR) feasible. The combination of orthogonal frequency-division multiplexing (OFDM) as a wideband pulse compression modulation with a DAR architecture allows time dispersion effects to be mitigated for electrically-long antenna arrays. This concept can be extended to the simultaneous operation of multiple radar modes. Each mode is allocated some number of OFDM subcarriers. The subcarriers corresponding to a particular mode are then phase-shifted to create an element-to-element phase shift across the antenna array to steer the full-aperture antenna beam for that particular mode. This concept multiplexes the modes in the frequency domain while the OFDM-based DAR allows each mode to experience the full-aperture gain on transmit and receive while being electronically steered to an independent spatial position.
This paper presents a missile tracking and detection using SAR and MIMO Radar signal processing. SAR is a technique for computing high-resolution radar returns that exceed the traditional resolution limits imposed by the physical size, or aperture, of an antenna. By using Kaiser Window, the trade off exists between the main lobe width and the side lobe amplitude. Kalman filter is used to minimizing the maximum error between the frequency response of the filter & the response of the ideal filter.
Abstract: Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Digital multiple beam forming on each antenna element about large phased array radar is impossible in processor based digital processing units, because it needs simultaneous processing many A/D channels.In this project we resolve this problem by using a multi array based beam forming technique with multiplexed signal processing unit on FPGA. The conventional technique of completely duplicated hardware and also dynamic reconfiguration does not yield the real time parallel beam processing. The proposed technique employs multiplexed signal processing unit which is time shared for various beam formers. This technique provides simultaneous beams without any compromise on functionality. The scope of the work includes the VHDL modeling of 16 element phased array antenna system and RTL implementation of complex NCO, digital mixer, low pass filter, multiplexers, demultiplexers, ROM for coefficient storage and Multiplier unit. The VHDL simulation of all these blocks shall demonstrate the beam formation for multiple beams. Simulated antenna outputs are used to test the developed beam former. The design is functionally verified by simulating the code in ModelSim from Mentor Graphics. The FPGA synthesis is done using Xilinx ISE tool. The synthesis results of ISE are analyzed for timing and area. The hardware output i.e FPGA output shows on Chipscope pro analyzer.
The FMCW Radar is widely used Radar for detecting the object and its velocity in various applications. Before an actual implementation of the FMCW Radar, it is essential to find out the correct combination of the components in the environment comprising noise and losses. The Radar system is analyzed using a SystemVue Software. Real-world impairments such as channel losses, propagation, and attenuation losses, nonlinearities of the system elements such as phase noise and mixer leakage have been incorporated into the simulation. The simulation helps to predict the results of the system before an actual development and saves development time. The velocity of the target (object) as well as its range is calculated using data flow technique in SystemVue.
