The paper presents a comparison of three different computing platforms for signal processing in Passive Coherent Location radar: general-purpose PC, Sony Play Station 3 and NVIDIA graphic card with CUDA technology. The radar under consideration was developed at Warsaw University of Technology, and it is called PaRaDe (Passive Radar Demonstrator). It utilizes commercial FM radio transmitters as illuminators...
Passive Coherent Location (PCL) radar measures the bistatic parameters of a target: the time difference of arrival and the Doppler shift. In order to localize a target in the Cartesian coordinates, the data from multiple transmitter-receiver pairs can be used. This task is, however, challenging due to the ambiguities in the measurements assignment. In the paper, a tracking algorithm is presented,...
This paper investigates various factors influencing the processing gain obtained thanks to coherent integration in a passive coherent location (PCL) radar. In theory, a longer integration time should lead to higher integration gain. In practice, however, some limitations exist, which restrict the maximum attainable processing gain. The paper presents theoretical considerations accompanied by numerical...
The paper presents a method for estimation of acceleration in passive coherent location (PCL) radar. The method is based on the Generalized Chirp Transform, which is a maximum likelihood estimator in this case. The authors propose a fast and efficient algorithm for calculating acceleration by filtering a two-dimensional range-Doppler surface. The algorithm is tested on simulated data as well as on...
The paper presents digital beamforming for Passive Coherent Location (PCL) radar. The considered circular antenna array is a part of a passive system developed at Warsaw University of Technology. The system is based on FM radio transmitters. The array consists of eight half-wave dipoles arranged in a circular array covering 360deg with multiple beams. The digital beamforming procedure is presented,...
The paper present a concept of a simple MIMO (multiple input multiple output) PCL (passive coherent location) radar relying on FM radio transmitters of opportunity. The use of MIMO approach instead the classical phased antenna results in significant increase in surveillance volume without changing requirements for computational power.
