General-purpose shared memory multicore architectures are becoming widely available. They are likely to stand as attractive alternatives to more specialized processing architectures such as FPGA and DSP-based platforms to perform real-time digital signal processing. In this paper, we show how we can ease parallelism expression on shared memory multicore architecture through the XPU high-level p...

This paper describes the design of a high performance 77GHz millimetre wave radar, signal processing and control system for use in autonomous vehicle navigation. The radar front end and intermediate frequency components are described together with a method of distinguishing pre-placed target beacons from other reflectors using the polarisation of the reflected signal. Digital signal processing ...

This paper introduces to the lecture series dedicated to the knowledge-based radar signal and data processing. Knowledge-based expert system (KBS) is in the realm of artificial intelligence. KBS consists of a knowledge base containing information specific to a problem domain and an inference engine that employs reasoning to yield decisions. KBS have been built: some are very complex with thousa...

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 proces...

We report on a technique for the radar ship signal extraction from contaminated sea clutter. Group normalization (GN) is presented to overcome that conventional wavelet packet coefficients not appropriately represent the strength of signal. The l entropy is extended to l one to improve the performance. The symmetric, complex wavelet packets are used for radar signal processing.

In this paper the echo signal of a moving pedestrian will be considered as an example of a velocity extended radar target. Based on measurements and simulations, target characteristics inside the radar receive signal differing from a point-target model will be analyzed and the necessity of new and alternative signal processing strategies for close-up applications will be shown.

Matched-filter is widely used in real time signal processing, especially in Radar Signal Processing. This paper provides a novel structure of digital matched-filter used in tracking radar system. This design applies block-floating-point arithmetic to improve the precision. The whole digital matched-filter is implemented in only one chip of FPGA. This ASIC has two work modes: 512 points pulse co...
