“…To detect a predefined signal in a received noisy signal that is shifted due to the Doppler effect, the 2D cross-correlation function of the two signals have to be calculated while one of the signals is copied with Doppler shift. Its discrete time 2 ) is the complex conjugate of the signal pattern we are looking for in the n, f d domain [12]. The procedure is done on blocks of signals, which have N samples.…”

In this article a novel method for satellite identification is presented for picosatellites. Utilizing apriori knowledge of the transmitted signals the cross-correlation of the received signal and a known transmission is calculated, from the results the Doppler shift is estimated and the satellite’s Doppler curve can be matched against the measurements of NORAD. Using this method an omnidirectional antenna can be used instead of a high gain directional antenna, and the gain difference is compensated by the processing gain of the algorithm described. The practicality of the algorithm is demonstrated through the mission of MRC-100 PocketQube.

A passive bistatic radar system is an application field of radar that detects and estimates a target using commercial broadcasting signals. It does not require the installation of a transmitter and provides mobile receivers. Since the location of the receiver can be changed, it is expected that the detection performance of the target will vary depending on the arrangement of the receivers. In order to improve the detection performance of the target, it is necessary to arrange the receivers in the proper locations. A bistatic radar system usually estimates the location of a target using three transmitters and one receiver. However, in an environment using a single receiver, there arises a situation where location estimation can not be performed when a target is out of

“…In recent years, passive bistatic radar (PBR) has become an emerging technology owing to its covert detection and lower cost compared to active radar systems. Therefore, many kinds of illuminators are exploited as transmitter, such as FM radio [1][2][3], television [4], satellites [5,6], cellular phone downlink [7,8], WIFI [9,10], digital video broadcasting, and digital audio broadcasting [11][12][13]. However, these researches mainly focus on civil illuminators.…”

Passive bistatic radar (PBR) has attracted widespread attention for its capabilities in dealing with the threat of electronic countermeasure, stealth technology, and antiradiation missile. However, passive detection methods are limited by unknown characteristics of the uncooperative illuminators, and conventional radar signal processing algorithms cannot be conducted accurately, especially when the carrier frequency of the transmitting signal is agile and the signal-to-noise ratio (SNR) in the scattered wave of target is low. To address the above problems, this paper presents a novel weak target detection method based on probability histogram, which is then tested by a field experiment. Preliminary results indicate the feasibility of the proposed method in weak target detection.
