Experimental results of aircraft positioning based on passive primary surveillance radar

Abstract

This paper describes an activity of passive surveillance system in Japan. Electric Navigation Research Institute (ENRI) started the feasibility study of the passive surveillance system to be a conventional primary surveillance radar (PSR) alternative. The representative system among its technologies is a multi-static primary surveillance radar (MSPSR) which achieves higher update rates and higher detection rates including low level flights than those of the current PSR. The MSPSR is classified into passive bi-static radar (PBR), and it is operated by combining some transmitters or some receivers. Radio waves of the conventional PSR are suitable resources of operating frequency. Therefore, ENRI has investigated passive PSR. In this paper, we introduce our recent works and show some results of experiments carried out in the Sendai and Nagoya areas in Japan. In the experiments, we investigated the advantages of the passive PSR. First, we introduce experimental environment and experimental setup. Next, we show experimental results. Results show high performance of the passive PSR system where the passive secondary surveillance radar (SSR) was unable to carry out positioning. Finally, we discuss the passive PSR potential.

A study of direction finding method for passive airport surveillance radar

“…It uses the phase differences in frequency component. Is is important that they picked up a signal for DF calculation include the reflected wave from aircraft and the passive PSR system using the PSR rotation information have already developed [4]. From these results, a passive PSR system without the PSR information, is possible to calculate the object position.…”

“…The distance from receiver to target is estimated by the elliptical positioning method. Therefore, the target position is calculated from the PSR beam angle and the elliptical range [4]. The synchronizing the PSR rotating cycle is an important function of prototype passive PSR receiver.…”

Improved probability hypothesis density filter for multi‐target tracking of non‐cooperative bistatic radar

“…Non-cooperative bistatic radar refers to the passive bistatic radar using a non-cooperative radar as the illuminator of opportunity, such as the air traffic control radar [1][2][3][4][5], the airport surveillance radar [6,7], the airborne early warning radar [8,9], the weather surveillance radar [10], the long range air surveillance/defence radar [11,12], the shore-based maritime surveillance radar [13], the low probability of intercept radar using frequencymodulated continuous wave [14], and the phased-array radar [15,16]. Compared with the conventional active monostatic radar, the non-cooperative bistatic radar has many advantages.…”

Weak Target Detection Method of Passive Bistatic Radar Based on Probability Histogram

“…Compared with the aforementioned transmitters, a dedicated radar usually has a higher power and a better range resolution [14][15][16][17]. At present, with the rapid development of the radar technology, frequency agile and phased array radar has attracted much attention because of its advantages of anti-jamming and high detection probability.…”
