This section gives a short survey of the principles and the terminology of phased array radar. Beamforming, radar detection and parameter estimation are described. The concept of subarrays and monopulse estimation with arbitrary subarrays is developed. As a preparation to adaptive beam forming, which is treated in several other sections, the topic of pattern shaping by deterministic weighting i...

In this paper different CFAR detectors for detection of multiple targets for UWB radar system will be described and their outputs compared. The cell averaging CFAR (CA-CFAR) cell averaging with greatest of (CAGO-CFAR), ordered statistics CFAR (OS-CFAR), clutter map CFAR (CMCFAR) and cell averaging CFAR assumed for gamma distributed clutter will be represented. The properties of all detectors wi...

This paper investigates techniques for angular superresolution using limited data of real beam scanning radar (RBSR). In order to improve the angular resolution of RBSR, many algorithms have been proposed. However, for most algorithms, large amounts of sampling data is necessary. The requirement of data increases the burden of the radar system. Fortunately, the sparse signal reconstruction tech...

In this paper, two suboptimum detectors are proposed for coherent radar signal detection in K-distributed clutter. Assuming certain values for several initial moments of clutter amplitude, the characteristic function of the clutter amplitude is approximated by a limited series. Using the Pade approximation, it is then converted to a rational fraction. Thus, the pdf of the clutter amplitude is o...

This work was carried out to improve the probability of interception of frequency sweep and lower the system complexity of non-sweep mode of the electronic intelligence system for frequency agile radar signal. A low complexity receiver structure and its associated demodulation algorithm with high probability of intercept are also presented. Moreover, the applicability of this structure for the ...

The passive radar is a hot research topic. A multi-channel wideband passive radar experimental system is designed and the digital television terrestrial broadcasting (DTTB) signal is chosen to carry out the target detection experiment of civil aviation aircraft. The polarization and spatial filtering methods are used to solve the strong direct path interference suppression problems brought by t...

Emerging requirements for several radar applications call for highly-specialised signal processing algorithms displaying good multi-user capability. The theoretical basis of the implicit sampling averaging algorithm implemented in the radar receiver and its use for time delay determination has been described by Szajnowski [3]. The CSR utilises chaotic or truly random continuous binary waveforms...

The first RADAR patent was applied for by Christian Huelsmeyer on April 30, 1904 at the patent office in Berlin, Germany. He was motivated by a ship accident on the river Weser and called his experimental system ”Telemobiloscope”. In this chapter some important and modern topics in radar system design and radar signal processing will be discussed. Waveform design is one innovative topic where n...

The calculation of wideband digital beamforming using traditonal methods is so large that it is hard to realize in project. This paper describes a wideband digital beamforming method on the base of stretch processing for linear frequency modulated (LFM) waveforms. This method offers advantages that are moderate data rate for wideband signal processing by reducing the signal bandwidth greatly. I...
