Title (EN) METHOD AND APPARATUS FOR TESTING SURVIVAL RADIOS
(FR) PROCEDE ET APPAREIL DE CONTROLE DE RADIOS DE SURVIE
Abstract: front page image
(EN)A test apparatus which is particularly adapted for testing survival-type radio transmitters in the field. The apparatus includes an enclosed metallic test chamber (10) into which the antenna (39) of the radio transmitter (22) is placed. A movable load carriage (100) within the chamber applies a load (111) to a predetermined point on the antenna which results in simulating in the test chamber (10) the radio frequency absorption/reflection characteristics of the antenna in free space. A direct measurement of the radio frequency energy absorbed by the load (111) is thus indicative of the performance of the radio transmitter (22) and its antenna (39) in free space.
(FR)Un appareil de controle est particulierement adapte pour controler des emetteurs radios du type survie sur le terrain. L"appareil comprend une chambre de controle metallique fermee (10) dans laquelle l"antenne (39) de l"emetteur radio (22) est placee. Un chariot mobile de charge (100) dans la chambre applique une charge (111) en un point predetermine de l"antenne ce qui a pour resultat de simuler dans la chambre de controle (10) les caracteristiques d"absorption/reflexion des frequences radios de l"antenne dans l"espace libre. Une mesure directe de l"energie de frequence radio absorbee par la charge (111) represente ainsi une indication de la performance de l"emetteur radio (22) et de son antenne (39) dans l"espace libre.
