An Improved Radar ECCM Method Based on Orthogonal Pulse Block and Parallel Matching Filter

Extending the Radar Dynamic Range using Adaptive Pulse Compression

The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...

A New Method for Ground Moving Targets Tracking Using Radar Based on Compressed Sensing

In this paper, we propose a Compressed Sensing (CS) based method under the unknown sparse degree to track ground moving targets using Pulse-Doppler (PD) radar. We use the sparsity of delay-Doppler plane in the process of disposing PD radar echo to set up a sparse signal model in each pulse interval. At the state prediction stage, we can get the predicted values of target states by dynamic equat...

A Design of the Matched Filter for the Passive Radar Sensor

This paper discusses a method of designing a matched filter for a passive microwave sensor. This sensor receives pulse signals transmitted by a target active radar. Received signals can be categorized into two types due to either the pulse signals or noise. The method first estimates an autocorrelation function of the received signals. The autocorrelation of the pulse signals is then extracted ...

Tracking Radar Digital Matched-Filter ASIC Design

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...
