Abstract: Изобретение относится к области радиолокации, конкретно к способу измерения угла места (УМ) воздушного объекта (ВО) в метровом диапазоне электромагнитных волн с помощью вертикальной антенной решетки (АР). Техническим результатом изобретения является повышение точности измерений угловых координат маловысотных ВО в «зоне их нечувствительности θ» при углах места, сравнимых с шириной диаграммы направленности приемной угломестной АР. Способ измерения угла места ВО заключается в приеме с помощью вертикальной N-канальной АР прямых и отраженных от подстилающей поверхности Земли предполья АР радиосигналов ВО, реальных сигналов и массива их квадратур.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to the field of medicine, namely to urology. The urethra is exposed along the entire length, followed by the formation of a submucosal tunnel 3.0 cm long from the clitoris to the external urethral opening and moving the distal urethra under the clitoral legs and fixing it beyond the edges of the opening, followed by the imposition of the first two sutures with the capture of the posterior urethral wall through all layers, with the exception of the mucous membrane, when restoring the integrity of the vagina. At the same time, before surgery, the presence of connective tissue dysplasia-HSD is determined. Then, before the urethra is released, a 0.25% ropivacaine solution is injected paraurethrally at 3 and 9 o'clock of the conventional dial. After the urethra is exposed, in the presence of a gaping meatus, its diameter is measured, and if it is 6-10 mm, then, departing 0.5 cm from the meatus, a horizontal U-shaped suture made of absorbable suture material is applied along the posterior surface of the urethra, without capturing the mucous membrane. Wherein if the diameter of the urethra is more than 10 mm, then a wedge-shaped resection of the distal third of the urethra along the ventral surface is performed. In this case, the integrity of the urethra is restored by imposing a continuous suture from absorbable suture material, without entrapment of the mucous membrane. A biodegradable collagen membrane is placed on the lower semicircle of the urethra and fixed, and this is done only for patients with HSD. Foley's urethral catheter is placed in a semicircle above the external opening of the urethra. 
     EFFECT: method makes it possible to assess the size of the external gaping opening of the urethra and the possibility of its reduction, to increase the immobilization of the external opening of the urethra in patients with HSD, to reduce the compression of the urethral catheter on the underlying paraurethral tissues in the early postoperative period, which makes it possible to reduce the number of patients in whom attacks of postcoital cystitis persist in postoperative period, to reduce the risk of recurrence, which will improve the quality of life of patients, reduce the trauma of the operation and postoperative pain syndrome.
