Abstract: FIELD: radar ranging. 
     SUBSTANCE: invention relates to radar and is intended for detection of a signal reflected from an air target, against a background of a direct probing signal from a radio transmitter, and signals reflected from stationary objects. In the method of spatial compensation of direct and reflected signals when a reflected signal is detected from an air target by a bistatic radar system, a radio transmitter transmitting the probing signal is used, and a radio receiver comprising an adaptive antenna array (AAA) consisting of antenna elements, a beam-forming circuit with weight coefficients, an adaptive control pattern and an adder unit. Method comprises emitting a probing signal by a radio transmitter, receiving a radio signal from a radio target reflected from an air target, as well as direct sounding signal from radio transmitter and signals reflected from stationary objects. At the output of the adder, using the recursive estimation of the weight coefficients vector, the signal s(t)=W H (t)X(t) is output, where X(t) is a vector of complex signals x n (t), n = 1, 2, … , N in AAA channels, N is the number of antenna elements, W H (t) is the transposed and complex conjugate vector of weight coefficients w 1 , w 2 ,… w N , W(t)=W(t-1)+kG(t), t – time counts, k – scalar gain factor. For k<0, AAA provides minimization of power, while k>0 provides maximization. Providing detection of a weak radio signal reflected from an air target against the background of strong interfering signals is achieved using a variable amplification factor determined depending on the gradient of the mean square of the output signal s(t). 
     EFFECT: high rate of adaptation and low dispersion of residual noise at low ratios of signal amplitude reflected from target, to amplitudes of interference signals.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to experimental medicine, military field surgery and traumatology, and can be used to simulate an explosive injury to the soft tissues of a limb, aggravated by blood loss. Trauma is made to the previously trimmed surface of the thigh of a small laboratory animal under anesthesia - a rat. Trauma is inflicted by organizing an explosion by detonating an explosive charge, which is used as a pyrotechnic product for household use - an ordinary grating firecracker Korsar-2, which is installed in the rat's thigh at a distance of 1.0-1.3 cm from the bone in a channel with a length of 2.0 -2.5 cm, formed in the area of the location of the semitendinosus, semimembranosus and biceps muscles of the thigh through a linear skin incision 0.8-1.0 cm long, made in the middle third of the lateral surface of the rat's thigh parallel to the longitudinal axis of the femur, for which a blunt method using clamping, minimally traumatizing the tissue, push apart the skin and exfoliate the muscles of the thigh. The Korsar-2 firecracker is installed in such a way that part of it protrudes 2 cm above the skin surface from the place of the fuse, and the remaining part is located in the formed channel and partially protrudes 0.3-1.0 cm from the counterperture on the opposite surface hips. Additionally, it is envisaged to aggravate the injury due to the production of blood loss in the amount of 15% of the circulating blood volume - CBV - by taking blood that poured out from the wound immediately after the injury is inflicted, and from the vessels of the rat tail after cutting off its part. From the tail, take the amount of blood that is missing up to 15% of the CBV, calculated on the basis that the CBV is 6.5% of the rat's body weight. To simulate an isolated explosive injury of the soft tissues of the limb, aggravated by blood loss, rats with a body weight of 320 ± 30 g are used. 
     EFFECT: method makes it possible to simulate explosive damage to the soft tissues of the thigh, aggravated by blood loss in the amount of 15% of the CBV, in small laboratory animals (rats) by organizing an explosion by detonating explosive charges, which are used as ordinary grating firecrackers, as well as obtaining the required volume of blood by sampling her from a wound received as a result of an explosive injury, and when part of the tail was cut off.
