Abstract

The invention concerns a method and system for testing radar systems' capability to detect and track targets. In particular, the method comprises defining a first non-linear trajectory of a non-linear moving target to be simulated, wherein said first non-linear trajectory comprises a sequence of first positions, each defined by respective range, azimuth and elevation with respect to an antenna (1) of a radar system under test. The method further includes computing a second non-linear trajectory based on the first non-linear trajectory. Said second non-linear trajectory comprises a sequence of second positions, each of which is defined by respective range, azimuth and elevation with respect to the antenna (1) of the radar system under test, is associated with a corresponding first position defined, with respect to the antenna (1) of the radar system under test, by the same azimuth and elevation as said second position and by a greater range than said second position, and is associated with a corresponding time at which the non-linear moving target is located at the corresponding first position associated with said second position. The method further includes: providing a drone (21) equipped with an on-board antenna (212) for receiving radar signals transmitted by the antenna (1) of the radar system under test; and flying the drone (21) by following the second non-linear trajectory and by causing said drone (21) to be located at each second position at the corresponding time associated with said second position. Additionally, the method includes also: when the drone (21) is located at one of the second positions, processing an incoming radar signal received by the on-board antenna (212) at said second position so as to generate a processed radar signal simulating a radar echo from the non-linear moving target located at the corresponding first position associated with said second position, and transmitting the processed radar signal by the on-board antenna (212) from said second position towards the antenna (1) of the radar system under test.
