This paper report on the development and field trial of a dual-band and dual-use system based on a single photonics-based transceiver and a single radiating element, able to simultaneously carry out radar and communication functionalities. The coexistence of the two operations does not introduce any penalty on the system performance. The innovative sharing of both transceiver and antenna element allows for a reduction in terms of cost and Size Weight and Power consumption. The dual-use radar-communication system has been demonstrated in a outdoor field trial combining a radar experiment in S-band and C-band OFDM (Orthogonal Frequency Division Multiplexing) communication.

The paper presents a multivariate copula approach to identify the dependence between different polarimetric parameters. This approach can be used to develop a new method of invariant polarimetric classification of radar targets. Signals from meteorological target are processed as an example.

This paper focuses on the estimation of target motion parameters in forward scatter radar. A new method based on the use of the Doppler signature spectrogram has been investigated. This allows a rough estimation of target motion parameters even in the presence of significant clutter, when the Doppler signature cannot be used to extract accurate kinematic information. The spectrogram characteristics change depending on target's speed, crossing angle and crossing point, this will be shown in order to explain how it is possible to estimate kinematic information analyzing the spectrogram trend. The performance of this new method is analyzed at the initial stage of the research.

This report proposes a detection method based on using kurtosis and maximum amplitude information, both extracted from the spectral domain. At the end we face a classification problem which is solved by introducing a linear decision boundary. This new method is proved to result into overall good and stable detection results.

Compressed sensing is a novel technique of under sampling sparse or compressible signals using random linear non adaptive measurements. Under the sparsity constraints it allows for reconstruction of the data with small or zero error using minimum l1 norm reconstruction methods. Since most of the real world data are either sparse or compressible in some suitable basis, the proposed method has immediately found application in varied fields like imaging systems, MRI, Radar systems etc. But most of the applications considered in literature deal with real data. For radar applications the data is complex and suitable amendments for processing are considered. In this paper we proposed an application of compressed sensing towards portable radar signal processor. We have used the method to accurately detect target's range and doppler with highly reduced quantum of input data. Since the doppler information is corrupted during the signal transformation to lower dimension we have used a parallel processing channel for estimating the doppler information.

This paper deals with the local optimization of the periodic or aperiodic ambiguity functions of a set of complex sequences by using a gradient method. This optimization aims to locally minimize the cross-ambiguity and the auto-ambiguity functions of a family of sequences for Multi-Static Primary Surveillance Radar (MSPSR) systems. The optimization of the ambiguity functions is done by an optimized gradient. An extension is also presented for controlling both the spectrum and the ambiguity functions.

The widespread availability of consumer grade drones in the recent time has lead to new security and surveillance challenges. The detection and localization of these unmanned aerial vehicles (UAV) mark an essential step to identify possible risks at an early stage before taking appropriate countermeasures. This paper describes the results of an experimental trial conducted to examine the detectability of small UAV using a GSM (Global System for Mobile Communications) based passive coherent location (PCL) system.

A wide band dual arm slot spiral antenna operating over 600 MHz to 3000 MHz was designed and tested for a Stepped Frequency Ground Penetrating Radar (SFGPR) application. This antenna is low profile, planar, uses a simple current element as the balanced feed. The influence of the receiver Intermediate Frequency (IF) Band Width (BW) on the Signal to Noise Ratio (SNR) for antenna operation under SFGPR mode is investigated for a metal rod buried inside dry sand.
