Abstract

The objective of this work is to determine the bistatic angle from which independent random samples can be obtained. It also investigates the degree of correlation of the backscattered signals as a function of the spatial distribution of the receiving points and their time difference of arrival when using a multistatic radar system. Obtaining large, independent random samples is a crucial requirement for applying and developing the DRACEC method, which is used for detection in moment space based on a Gaussian distribution. This requirement is challenging to meet due to the prohibitively long acquisition and processing times involved. However, it becomes feasible through the use of multiple receivers, which enable the simultaneous acquisition of large, independent random samples. Furthermore, this work develops a simulation of the secondary emission correlation as a function of the bistatic angle, considering the baseline length between the transmitter and receiver and the angle between them. An exhaustive analysis is also performed of the spatial and temporal correlation function of the signal fluctuations from a radar target in a Multistatic Radar System (MRCS) comprising one transmitter and two receivers. Finally, this work derives approximate expressions for determining the correlation coefficient, as well as the approximate conditions for high and low spatial and temporal correlation of the echo fluctuations at the input of the MRCS receivers.
