\(\Delta R = \frac = 30 meters\)Ī staggering improvement in range resolution by a factor of 5. Our pulse width will be equal to \(1\mu s\) resulting in a range resolution of, The radar pulse repetition frequency would be set to 10kHz resulting in a maximum unambiguous range of 15km. The LFM pulse will have sweep bandwidth of 5MHz. Additionally, we shall be transmitting a pulse with Linear frequency modulation for pulse compression. The transmit power will be set at 5W and receiver preamplifier gain set to 10dB with a noise figure of 5. Let us define a few things related to the radar before we proceed. For example, the transmitter, the antenna system, the target itself and so on. In order to simulate a radar system in Matlab, you need to have everything defined. I tried the phased array toolbox for the first time to build a pulsed radar which can determine approximate azimuth angle of the target with respect to the radar. With so many tools at your disposal, the phased array toolbox lets us build a complete end to end radar system. Reference examples provide workflows for generating HDL code from Simulink ® models.The Matlab phased array toolbox is a collection of many interesting algorithms and functions. The toolbox also provides continuous and pulsed waveforms that you can use to generate test signals and simulate target echoes, interferences, and propagation effects.įor simulation acceleration or desktop prototyping, the toolbox supports C code generation. You can simulate multipath fading environments to test the performance of beamforming antenna arrays.įor radar, sonar, and acoustic system design, the toolbox includes signal processing algorithms for beamforming, space-time adaptive processing (STAP), direction of arrival (DOA) estimation, matched filtering, and signal detection. The toolbox includes algorithms for simulating hybrid and full digital beamforming architectures for massive MIMO and millimeter wave systems. Simulated signals can be transmitted and received by these arrays for beamforming and signal processing algorithm design.įor 5G and LTE cellular, SATCOM, and WLAN communications systems, you can design multibeam and electronically steerable antennas. You can model and analyze the behavior of active and passive arrays, including subarrays and arbitrary geometries. Phased Array System Toolbox™ provides algorithms and apps for designing and simulating sensor array and beamforming systems in wireless communication, radar, sonar, acoustic, and medical imaging applications.
