By decoupling the software and hardware, the software and cognitive radar (SRadar&CRadar) support the alteration of their functions by remapping different software in a uniform platform. This feature can make the radar more flexible, and has become a significant trend of the radars. In order to map efficiently, a framework including resource model and mapping algorithm is needed, which has been...
This paper concerns the identifiability of antenna position errors in MIMO radar array shape self-calibration. Self-calibration is accomplished with the aid of far-field targets whose DOAs and scattering coefficients are initially unknown. By deriving and analyzing the hybrid Cramer-Rao bound (HCRB) of antenna position errors, we proved the following conclusion: with a position reference, for MIMO...
This paper investigates the lifetimes of the objects used by Radar signal processing(RSP) systems and classifies them into temporary objects and persistent objects. Based on this classification, we propose a memory allocator which is well suited for embedded RSP systems. It is shown that this allocator has constant response time and introduces neither internal nor external fragmentations.
Radon-Fourier Transform (RFT) has been recently introduced as an effective method for long-time coherent integration of moving targets. In this paper, analysis of RFT in clutter background is proposed to prove its capability to separate targets from clutter. Furthermore, the signal-to-clutter ratio (SCR) Improvement Factor of RFT is introduced and calculated. Then, according to the SCR Improvement...
Based on Stein's lemma, we use relative entropy as a measure of error exponent to study detection performance of Neyman Pearson (NP) detectors for both multiple-input multiple-output (MIMO) radar and phased array radar. In high signal-to-noise ratio (SNR) region, we introduce the concept of diversity order to get insights of results. In low SNR region, we give instructive approximations for analytical...
Based on Steinpsilas lemma, we use relative entropy as an error exponent measure to study the detection performance of Neyman Pearson (NP) detectors. Both multiple-input-multiple-output (MIMO) radar and phased-array radar are investigated. We introduce the notion of diversity order to get the insights of results. For a bistatic radar where the transmitters and receivers are deployed separately with...
